A North Carolina unit is the first in the National Guard to field test the new SIG Sauer-made XM7 and the XM250, which is replacing the M4/M4A1 carbine and M249 Squad Automatic Weapon, respectively.
The 30th Armored Brigade Combat Team, a National Guard outfit that carries the “Old Hickory” lineage of the World War I & II era infantry division of the same number, earlier this month conducted a qualification table range session with the Army’s Next Generation Squad Weapon platforms at Fort Liberty (formerly Fort Bragg), North Carolina.
The unit is the first in the Guard to receive the XM7 and XM250, just months after the first regular Army unit, the famed 101st Airborne Division, began receiving their NGSWs.

This comes as ADM Daryl Caudle, commander of the U.S. Fleet Forces Command, toured SIG Sauer’s new Academy and SIG Experience Center in Newington, New Hampshire, earlier this month. Images released by the Pentagon show Caudle and staff inspecting the state-of-the-art facility where over 480,000 M17 and M18 handguns have been produced for the military thus far.
And include Caudle handling an NSGW.

Of note, the Marines have been interested in the platform going back to 2020.
Part of the famed 101st Airborne Division recently became the first unit issued with the new Next Generation Squad Weapon system.
A March 28 social media post from the PEO Soldier office detailed that the 1st Battalion, 506th Infantry Regiment, a unit of the Fort Campbell-based 101st, received the NGSW, marking a key milestone for the program that intends to replace the 5.56 NATO M4 Carbine and M249 Squad Automatic Weapon with a new family of weapons chambered in 6.8mm.
The new guns will be used in an upcoming New Equipment Training, an in-depth, train-the-trainer course, set for this month. From there, the systems and training will fan out across the brigade.
Elements of the 101st had been previously involved in an extensive series of more than 100 tests spanning over 25,000 hours and 1.5 million rounds of ammo with the platform.

The program includes SIG Sauer’s XM-7 rifle, which will fill the role currently held by the M4 series, the SIG XM250 light machine gun slated to replace the M249, and the Vortex-produced M157 Fire Control optics system used on both platforms. SIG also supplies suppressors for the platforms. Of note, the XM-7 is based on SIG’s MCX Spear series.
Next up for NGSW is to equip a National Guard armored brigade in May.
The only Arctic, Airborne, Recon cavalry squadron in the U.S. Army has been busy trying out the service’s new Next Generation Squad Weapon systems in some of the worst weather Alaska can offer.
The 1st Squadron (Airborne) of the 40th Cavalry Regiment, working with Fort Greely’s Cold Regions Test Center in one of the coldest parts of Alaska, has been putting the NGSW platform through its paces. The program includes SIG Sauer’s XM-7 rifle, which will fill the role currently held by the M4 Carbine series, the SIG XM250 light machine gun slated to replace the M249 Squad Automatic Weapon, and the Vortex-produced M157 Fire Control optics system used on both platforms.
“Extreme environmental testing is critical to ensuring reliable systems,” noted Col. Jason Bohannon, the Army’s Project Manager Soldier Lethality on Feb. 9.
Meanwhile, a social media page for the 1st Squadron-40th Cav noted that they have been experiencing “sub-Arctic conditions in the vicinity of Ft Greely where temperatures haven’t topped above -25 degrees.”

The 40th has a long military history of making it work under terrible conditions. Based in its current form in Alaska since 2005– from where they deployed to Iraq (Southern Baghdad) once and Afghanistan twice (Paktya and Khost Provinces)– it draws its lineage from the old 40th Tank Battalion which entered combat on August 15 1944 fighting across northern France into Belgium where it made a significant contribution to the defeat of German forces at St. Vith during the Battle of the Bulge then drove into Germany linking up with the Soviets on the Baltic coast.

The Army’s Next Generation Squad Weapons program just completed an important milestone with the SIG Sauer-produced firearms wrapping up testing at Fort Campbell, Kentucky.
First arriving in quantity at the base in early October, the NGSW just finished new equipment training and a limited user test with troops drawn from the 75th Ranger Regiment and the “Screaming Eagles” of the 101st Airborne Division.
The training started with classroom work on the new systems, including SIG Sauer’s XM-7 rifle, which will fill the role currently held by the M4 Carbine series, the SIG XM250 light machine gun slated to replace the M249 Squad Automatic Weapon, and the Vortex-produced M157 Fire Control optics system used on both platforms.

The Army’s Next Generation Squad Weapons program is rolling right along, with the SIG Sauer-produced firearms making an appearance at Fort Campbell, Kentucky.
The base, home to the iconic “Screaming Eagles” of the 101st Airborne Division, will be the first to field operational units with the new guns under current plans, and Campbell brass appeared on the firing line to get a feel for the new hardware.

As outlined by Soldier Systems Daily, Company A of the 2nd Battalion, 502nd Infantry Regiment, a historic unit that has been part of the 101st since World War II, will begin a Limited User Test with the NGSW platforms this week, comparing them to legacy systems. The Army plans to have the 101st’s 1st Brigade be the first unit fully equipped with the NGSW, likely sometime early next year.
The XM250, Sig Sauer’s light machine gun, is the tentative NGSW-AR winner. Like the XM5, it is chambered in 6.8x51mm. It is expected to replace the M249 SAW in front-line service with the U.S. Army. (Photo: Chris Eger/Guns.com)

The Army’s Next Generation Squad Weapon program– which is a big war battle rifle and light machine gun in a new (and very spicy) common 6.8x51mm caliber with a gucci optics package– is a thing.
As I’ve covered in the past several years, just about every large (and several small) rifle, ammo, and/or glass maker has tried to take a bite at the program, which stands to be the biggest small arms contract of the past 65 years.
Of course, the plan now is just to equip front-facing warfighters with the guns (spec ops, infantry, etc) rather than everyone, so the numbers are small, at least for now, but the potential to expand is great, especially if the program is successful and scalable.
Well, an op-ed piece by an Australian terrorism expert, without any clear first-hand experience with the guns or the programs, cast a mountain of shade on the system last month, something which should not have come as a surprise as he has ginned uphit pieces on the program in the past, which all kind of smacked from his personal feelings rather than something based in fact.
Then, the SIG and Vortex haters came jumping off the top rope on all the reddits, forum posts, blog posts, and gun groups saying that NGSW is a dead program and a colossal waste of time and treasure– all without citing any source rather than the articles written by said Australian terror expert (an academic who advocated scrapping the SAS of all things and that “the US may now be spinning dangerously towards insurgency).
However, the Army has responded with a press blitz of its own, coupled with the budget book asking for $300 million in funding for FY24 for the NSGW program. This will cover 1,419 M250 Automatic Rifle (NGSW-AR)s, 17,122 M7 Rifle (NGSW-R)s, and 14,932 M157 Fire Control systems, about one-sixth of what the Army plans to buy for the life of the multi-year program, numbers that sound about right.

So, for now, at least, it would seem that NGSW is very much still alive, no matter what the internet says.
As it stands the Army says it has conducted over 100 technical tests, fired over 1.5 million rounds of 6.8mm ammunition through the guns, and logged more than 20,000 hours of soldier testing with the NGSWs.
Next is Production Qualification Testing and Operational Tests this summer, followed by the first weapons headed to units in the second quarter of 2024.
I recently got to hang out with the folks from Sig Sauer and learned about the company’s successful submission to the Army’s Next Generation Squad Weapons program.
As part of Sig’s Freedom Days event at the Ben Avery Shooting Center outside of Phoenix, Arizona, the company had its MCX Spear and prototype XM250 light machine gun on display and available for attendees to shoot.
Jason St. John, a well-mustachioed retired Army Ranger and now Sig’s director for government products, took a break from holding class on the systems and gave us the 411 in the below three-minute video.
Some of the key takeaways:
The MCX Spear/XM5 has a low-profile buttstock that is both extendible and side-folding, providing soldiers a more compact firearm while riding in vehicles and aircraft. Nonetheless, it is still fully deployable with the stock folded. Attached with T27 Torx screws, it can be replaced with other stocks, and Sig has flavors including one with a gas mask cut and a six-way adjustable precision rifle stock. Alternatively, an M4-style tube can be fitted.
It is closer in size to a compact AR-10/SR-25 rather than an M4. St. John explained it as “an AR-10 version of the M4 version of the MCX,” in talking about the upscale. “There’s no way to go to a medium-caliber solution without moving up from a small-caliber rifle…you’re not going to get the performance from an M4-sized rifle, so it was inevitable that the rifle was going to grow.”
The rifle is about as ambi as it comes. This includes a selector lever, bolt catch/bolt release, and a magazine catch/release on both the left and right-hand sides of the lower receiver.
It has two charging handles – a rearward handle that is familiar to any AR/M4 user, and a side-mounted non-reciprocating charging handle on the left of the upper, akin to that seen on a G3/HK91 or SCAR NRCH. It folds to a low profile.
The MCX Spear has a user-swappable barrel and barrel extension held inside two T27 Torx screws in a self-contained clamp. Just loosen it up and swap it out for a shorter barrel or a different caliber. It doesn’t get much more modular than that. Sig has a commercial version of the gun in .277 Fury and 6.5 CM with .308 Win models coming soon. Sig also plans a Sig MCX Spear Rattler with an 8-inch gas trap barrel that, with hybrid ammo, will still provide carbine-like velocity.
For those quiet moments, the MCX Spear has a two-position gas valve – “normal” and “adverse,” each with its own suppressed and unsuppressed settings – that allows the user to tweak the gas system for different ammo types and field conditions. Keep in mind that the Army may have to use the rifle anywhere from the polar regions to the jungle and desert.
The XM250 has an extendable buttstock. Sig also offers the gun with a side-folding stock, so that already exists should the Army look for a more compact LMG down the road.
The charging handle is on the left side of the XM250’s receiver while the feed tray opens from the left as well, rather than the top as on some other machine guns. Sig said this is so the feed tray doesn’t interfere with in-line optics mounted on the gun’s top Pic rail.
The machine gun has a quick-change barrel with a self-contained clamp that can be changed in seconds. This feature also allows the gun to swap between its standard 6.8 caliber to, for instance, a 7.62 NATO caliber, in minutes.
Firing from an open bolt, the XM250 has a three-position safety: safe, full auto, and semi. Unlike other designs, it can be loaded with the bolt forward and charged with the selector on safe.
Like the MCX/XM5, the X250 has a two-position (“normal” and “adverse”) gas valve, each with suppressed and unsuppressed settings.
The hybrid bi-metallic case on the 6.8x51mm cartridge developed for the Army by Sig uses a steel base/head and a brass case to allow the pressure to go from the traditional ~68,000 psi of an all-brass case to the region of 120K psi without any failure while still using conventional primers and powder. This translates to a 350 fps boost in velocity. Alternatively, this also allows for 16-inch-barrel-level velocities from an 8-inch barrel or a 24-inch-barrel-level velo from a 14-inch barrel.

While initial media briefs on the systems set to replace the M4 Carbine and M249 SAW on the Army’s frontlines held back some details, the specs are now public.
The largest and most sweeping small arms program developed by the U.S. military since the 1950s, the Next Generation Squad Weapon initiative recently picked Sig Sauer to provide the XM5 rifle and XM250 light machine gun to replace the M4 and M249, respectively. Both weapons use Sig’s in-house developed SLX suppressor system and 6.8x51mm cartridge– sold on the consumer market as the .277 Sig Fury. Meanwhile, the platforms will use an integrated optics system developed for the purpose by Vortex.
A briefing by the Army last month immediately after the announcement that Sig was the tentative winner to supply the XM5 and XM250 was fuzzy when it came to weights and dimensions.
“So, I — so the weights are — I’ll give a comparison to the M4 and the 249 in general weight difference,” said Col. Scott Madore, PM Soldier Lethality when asked. “So, the rifle — the Next-Gen Squad Weapon rifle is about two pounds over the M4. Now the automatic rifle is actually four pounds less than the current M249 squad automatic weapon.”
Now the Army has released the figures, with the XM5 listed as 8.38 pounds, and 9.84 with its suppressor attached. The overall length, with the suppressor attached, is 36 inches with the side-folding stock extended and the standard 15.3-inch barrel. By comparison, the service lists the weight of the M4A1, complete with backup iron sight, sling, adapter rail system, and an empty magazine, as 7.74 pounds. The length of the M4A1 with its stock extended and without a suppressor is 33.82 inches.

Like the combat load of the XM5 compared to the M4, the XM250 user will carry fewer rounds at a heavier weight, described as four 100-round pouches, at 27.1 pounds. The M249 light machine gun combat load, which is three 200-round pouches, weighs 20.8 pounds.

Is the juice worth the squeeze? The Army thinks so, saying the benchmark for the 6.8 cartridge was that it weigh less per round than the 7.62 NATO.
With that in mind, in a very real sense, comparing the XM5/XM250 to the M4/M249 is an apple to oranges situation, and it may be more appropriate to journey back to about 1965 and compare the new guns to the M14 battle rifle and M60 machine gun, both of which were in 7.62.
The basic wood-stocked M14 hit the scales at 9 pounds empty and was, initially, carried with five 20-round magazines, later increased to seven mags. A 140-round combat load of 7.62 carried in seven steel M14 mags is 11.2 pounds, or about 1.5 pounds less than the same quantity of 6.8 as carried with the XM5.
A demo of the then-new M14 at Fort Dix in June 1959. Similar in size to the M1 Garand, with 29 of 116 parts interchangeable with that .30-06 semi-automatic rifle, the M14 was select-fire and had a larger, 20-round magazine. (Photo: Springfield Armory National Historic Site)
The M60, which was often derided as “The Pig” due to its weight, took cues from the German MG42 machine gun and, even with the use of early plastics in its furniture, weighed 23 pounds when introduced, although this was later whittled down to a more carry-friendly 18.5 pounds, both figures significantly heavier than the XM250.
A demo of the then-new M60 before troops. The 23-pound 7.62 NATO belt-fed machine gun replaced the awkward M1919A6 and was considered much lighter than the latter 32-pound weapon, so much so that it was demonstrated firing one-handed overhead. (Photo: Springfield Armory National Historic Site)
As noted by the Army, “The 6.8 mm has proven to outperform most modern 5.56mm and 7.62mm ammunition against a full array of targets.”
XM5 – Designation of the Sig Sauer NGSW-Rifle as adopted. The rifle, Sig’s MCX-Spear design, is intended to replace the M4 Carbine in use with “close combat forces.” Once it has been fully adopted and released, the “X” will fall off, making it the M5.

XM250 – Designation of the Sig Sauer NGSW-Automatic Rifle as adopted. The weapon, Sig’s Lightweight Machine Gun design, is intended to replace the M249 SAW Carbine in use with “close combat forces.”

It is reportedly four pounds lighter than the M249, while using a more powerful round with a greater effective range. (Photo: Sig Sauer)
XM157 – Designation of the Fire Control system, a separate contract awarded earlier this year to Vortex, to provide an integrated optic to be used on both the XM5 and XM250.
6.8x51mm – The Common Cartridge family of ammunition to be used by both the XM5 and XM250. The first types will be general-purpose, blank, drill/dummy inert, a reduced range training cartridge to allow the Army’s current ranges to be used, and high-pressure test rounds.
$4,500,000,000 – The total contract value if all options are taken for Sig Sauer to manufacture and deliver the XM5 Next Generation Squad Weapon Rifle, the XM250 NGSW Automatic Rifle, and the 6.8 Common Cartridge Family of Ammunition, as well as accessories, spares, and contractor support, over the next 10 years.
$20.4 million – Funds authorized for now to Sig covering weapons and ammunition that will undergo further testing.
$20 million – Amount of the contract awarded to Winchester earlier this year to plan the production of new NGSW ammo types at the contractor-run Lake City Army Ammunition Plant in Missouri. Lake City has already been providing projectiles for Sig Sauer and the other competitors to use on their cartridges during the prototyping phase.
$2.7 billion – Maximum amount of the 10-year contract to Vortex to provide the XM157 Fire Control optics system for the NGSW firearms. The Army said this week the weapons will be fielded as a system, with both the rifles and machine guns carrying the same optics and suppressors.
140 – The number of rounds carried by the average XM5 user. The XM5 ammo loadout is seven 20-round mags for a weight of 9.8 pounds, compared to the current M4 loadout of seven 30-round mags (210 rounds total) for 7.4 pounds, meaning XM5 shooters will give up 70 rounds and carry another 5 pounds in a total weapon, optic and ammo load compared to the M4.
400 – The number of rounds carried by the average XM250 user. The XM250 ammo load per automatic rifleman is four 100-round pouches weighing 27.1 pounds. Compare this to the current SAW gunner who carries three 200-round pouches (600 rounds total) for 20.8 pounds. In other words, XM250 light machine gunners will lose 200 rounds and add 3.6 pounds compared with the M249 SAW load. While the XM250 is lighter overall, the ammo is heavier and the new optic adds 2.6 pounds to the system.
16,348 – The number of XM5 rifles planned to be purchased by the Army in Fiscal Year 23.
1,704 – The number of XM250 machine guns planned to buy in FY23.
17,164 – The number of NGSW fire control modules planned to be purchased by the Army in FY23.
27 Months – The length of the Army’s rigorous testing and evaluation process prior to down-selecting Sig this week.
500 – Number of Soldiers, Marines, and special operations personnel involved in 18 touchpoints and more than 100 technical sub-tests during the past 27-month evaluation.
20,000 – Hours of user feedback garnered from Soldiers and Marines in the testing process.
120,000 – Soldiers in the Army’s active (COMPO 1) and reserve (COMPO 2) close combat force– identified as infantrymen, cavalry scouts, combat engineers, medics, special operations, and forward observers– who will use the NGSW platforms. Army spokesmen this week said other units and specialties will continue to use legacy small arms. “For example, the company supply sergeant will continue to carry M-4 or another weapon, not the Next-Gen Weapon.”
250,000 – Current ceiling of NGSWs in the contract. With that being said, the Army stated this week the current thinking is to field 107,000 M5 rifles and 13,000 M250 machine guns initially, roughly an 8:1 ratio.
Two pounds — The weight that the XM5 rifle is heavier than the current M4 it is set to replace.
Four pounds – The weight that the XM250 machine gun is lighter than the current M249.
3-to-5 Years – The length of time Sig Sauer will remain as the primary supplier of 6.8 ammunition to the Army as the military ramps up production at its own facilities. After that, it is expected the company will still provide ammo to the Army as a secondary source.
10 Years – Potential length of this week’s contract between Sig and the Army, broken into annual ordering periods.
65 Years – The last time the Army fielded a new weapon system of this nature– a rifle and machine gun along with a new caliber family of ammunition. The previous date was 1957 when the M14 and M60, in 7.62 NATO, replaced the M1 Garand, M1918 BAR, M1 Carbine, and M1919 machine gun.
2023 (3rd quarter) – When the Army expects its IOT&E– Initial Operational Test and Evaluation– a major program milestone that, will be completed on the NGSW, paving the way for full-rate production.
2023 (4th quarter) – The year the Army expects to equip the first unit with production NGSW variants, as detailed in a Pentagon press conference this week.
2026 – Expected start date of 6.8mm ammo production at a new building constructed specifically for the purpose at Lake City.
2029 – The theorized date mentioned by Army spokesmen this week when 6.8 ammo production “perhaps open it up to commercial vendors like we do with the other calibers.”
2032– The year this week’s Army NGSW contract with Sig concludes.
