As Close as it gets to an ‘Affordable’ Modular Carbine

Posted on by One comment

Modular 5.56 rifles are the way of the future. However, they are expensive by any measure. Just look at the Beretta ARX160, the FN SCAR, and the CZ Bren M2– the cheapest of which hit the low $2K mark and go far north from there.

Take for example the new SIG Sauer MCX Spear in 6.5 Creedmoor. While I dearly love SIG– my West German P226 has been shot out twice over the three two decades, each requiring a new breechblock and spring rebuild; while my daily carry pistol for most of the past six months has been a P365 XMac– they are very proud of their guns.

There is a lot to be proud of with the MCX Spear in 6.5 Creedmoor.

A kind of stepped-up version of the new MCX Spear LT, which was announced last year in 5.56 NATO, 7.62x39mm, and .300 Blackout, the new variants will be in .277 Fury, .308 Win, and 6.5, with the latter being the most interesting in my opinion.

The new rifles share the same broad strokes of the Spear LT, including AR trigger compatibility, a push-button folding stock, fully ambi controls, dual charging handles (left side non-reciprocating and rear AR-style), SIG’s SLX suppressor quick detach muzzle device, a full-length top rail, and the ability to swap bolt/barrels for caliber exchanges.

Couple that with a 6.5CM and you run a laser-accurate round capable of effective hits to 800 yards with little hold over

Of course, SIG says the gun will cost $4K, sans optics.

Enter the Israeli IWI Carmel, which is now in production in the U.S. as the prospect of importing it adds a lot of flies and 922R problems to the mix.

Complete with a folding stock, fully ambidextrous controls, and a rock-solid reliable short-stroke gas piston that keeps everything cleaner (and doesn’t use the gas ring systems of the SCAR), the soft-shooting Carmel will hit the $1,600-$1,800 range and be available later this year.

Also, it uses AR-15 mags. Boom.

SIG Rattler, now in 7.62x39mm for SOCOM?

SOCOM– which earlier this year for up to $5 million worth of “Reduced Signature” PDW weapons in the form of modified commercial SIG MCX Rattlers in both 5.56 NATO and .300 Blackout– posted the notice for 7.62x39mm uppers for the platform in late October.

“Due to developing requirements,” explains the notice, the force at the tip of the spear is seeking conversion kits to include all “required hardware and ammunition magazines that will fit with the SIG Sauer Rattler and RSAR/PDW converted M4A1 lower receiver groups.”

SOCOM may be in luck as SIG recently debuted their first 7.62×39-chambered offerings in the MCX Spear-LT series. One of the options in that series is a factory SBR with an 11-inch barrel and an overall length of 29.75 inches, something that puts the company within striking distance of the RFI notice.

SIG goes lighter, and more 7.62×39, for the MCX Spear LT

Posted on by Leave a comment

SIG Sauer developed the MCX series back around 2014 with a “particular customer in mind” and then transitioned it to fill both the demands of the military– the Army’s new 6.8mm Next Generation Squad Weapon-Automatic Rifle or NGSW-AR, adopted earlier this year as the XM5, is based on the MCX Spear, while SOCOM went with the shorty Rattler variant in 5.56/.300BLK — and the consumer market, namely with the MCV Virtus line. With a decade of success in the rearview, the company decided to, rather than sit on its laurels, to instead push the platform to the next level.

Meet the new MCX Spear LT, which brings back compatibility with standard AR trigger packs– opening a world of modularity lost with the Virtus– slimming the rifle down by about a pound, and delivering better ergonomics. Also, the new gun will be offered in eight different models, including carbines, pistols, and SBRs available in 5.56 NATO, .300 Blackout, and 7.62×39– the latter new for the platform and a caliber unusual altogether for SIG.

I got to play around with these in New Hampshire last month and was really impressed.
