Maxim Goes 22, Quietly

Folks have been turning the Ruger .22LR pistol into a suppressed specialty piece for generations. Heck, back when I got my first Form 4 approved over 20 years ago, it was for a dinky TAC65 can that I put on a circa 1950s Ruger Standard courtesy of a screw-on threaded coupler.

Going far past screw jobs, integrally suppressed Ruger 22 pistols are wicked quiet, like sub-BB gun sounding with standard velo ammunition and “Hollywood quiet” with subsonics. Mark Serbu, the Tampa Bay Wonka of gun craft, started his business making such guns even before he gained fame with the Serbu Super Shorty.

Dubbed the Serbu Sirius, it was a Ruger Mark II that had been completely rebuilt and I got to play with one back when I toured Serbu’s shop back in 2019.

Now, continuing the tradition it would seem, Maxim Defense is bringing in a whole line of suppressors and as part of that push has debuted its first .22LR pistol, and in traditional Maxim fashion, it isn’t ordinary.

The new Maxim MKIV-SD is based on the Ruger MKIV platform, which the company terms the “finest modern .22LR pistol in the world,” and adds an integrated suppressor it bills as the “quietest purpose-built suppressor in category with the easiest maintainability.”

Maxim Getting in the Long Game

Maxim Defense arrived at SHOT Show last week in Nevada with its new SR-25 style rifle, the MD:11, complete with options for a PROOF Research carbon fiber barrel.

The new MD:11 is a direct impingement AR-10 style rifle offered in 6.5 Creedmoor or .308 Winchester, with all models using either an 18-inch PROOF Research carbon-fiber or stainless-steel barrel set in billet 7075-T6 receivers with a floating 15.5-inch M-LOK slotted handguard. The lightweight barrel helps keep weight down to the 9-pound range.

Other standard features are a carbine buffer system, B5 SOPMOD stock, ambi surface controls, and Gisselle SSA-E trigger. I found it to be a laser on the range (Photo: Chris Eger/Guns.com)

Maxim says the MD:11 was initially designed for USSOCOM requirements. However, once the decision was made to commercialize the SOCOM requirement (within limits), 6.5 Creedmoor and .308 Winchester were deemed the best calibers.

I Recently Ran Across a Beautiful Beast of a Machine Gun Suppressor

One of the most interesting but least talked about aspects of Maxim Defense is its suppressor wing, and I talked to them about their almost spooky quiet GPMG can.

While on a visit to Maxim’s St. Cloud, Minnesota headquarters, spoke with CJ Dugan (late of certain Tier 1 groups) and the gang about the company’s suppressor team. Acquired after the great schism in the suppressor industry in 2017, Maxim’s quiet-time R&D crew includes such legends in the industry as Dr. Phil Dater.

By 2019, the company arrived at SHOT Show with a few prototypes of their integrated suppressed AR uppers as well as a very interesting can for the FN MAG 58/M240 series of 7.62 NATO general-purpose machine guns. Incorporating a series of patent-pending technology, it is treading harsh terrain that has broken other cans.

Besides holding up despite glowing red-hot– it has outlasted the machine guns it has been tested on– it is shown to drop the sound report to 135dB, which is quiet enough to talk in the vicinity of without ear pro.

Now, it is being tested by the Army, with good initial feedback. Not bad for a company that didn’t exist a decade ago.

Behind the scenes at Maxim Defense

One of the places I stopped at on my trip to Minnesota last month– in the 91-degree heat just a couple hours south of Canada?!– was Maxim Defense. For a company that didn’t exist seven years ago, they have really come out of nowhere and made a name for themselves.

They specialize in the “short space” so to speak, with products like the PDX.

The PDX had its origin in a PDW project for Tier 1 operators which specified a gun that, above all, was extremely compact for close quarter encounters– but still able to fire 5.56mm rounds. Crafted with that use in mind, Maxim’s result was a gun that is as sweet as it gets– just 18.75-inches long overall with a 5.5-inch barrel that ends in a Hatebrake muzzle booster while the collapsible stock is Maxim’s in-house SCW stock system. The PDX includes an integrated BCG with interchangeable buffer weights to maximize performance. (Photo: Chris Eger/Guns.com)
