SIG SAUER has updated the MCX line: new M- LOK rail, QD mounts and tapered barrel design. The redesigned M-LOK hand-guard system allows for easier access to the gas adjuster from the sides and front. Although the hand-guard is not compatible with previous generation MCX SBRs and pistols it’s . . .

extremely easy to remove. Push a pin and pull it off. You can adjust the two position gas adjuster by hand, with a screw driver from the top or a bullet.

On the heavier carbine calibers SIG featured the SIG716 G2 DMR in 6.5 Creedmor and 7.62 NATO. The AR features a gas piston system, integrated hand-guard to pic rail, Magpul PRS stock and the proprietary SIG Match Duo trigger.

If you want a complete SIG firearm down to the stock, SIG offers the M400 SDI line for rifles in several editions including a Kyle Lamb (VTAC) carbine.The carbine is also fully ambidextrous with a very convenient right-sided bolt release.

  1. So the exact same hand-guard removal system on the ACR from about 10 years ago, how innovative Sig… Coming in 2019 quick change barrels!!!

    • They’ve been using that handguard system since the MCX first came out, doofus. Same gun that launched with quick-change barrels.

  2. Loves me some 716.

    I only hate them for the 6.5 Creedmore, and by hate, I mean angry with SIG for verifying any shortcomings that may be evident in my disposable income.
