CMMG Dissent MK4 5.56 NATO 16.1" AR Pistol - Armored Black

The CMMG Dissent MK4 5.56 NATO 16.1" AR pistol brings modern ergonomics and shootability to a compact platform that doesn't sacrifice control or customization. Built on a direct impingement system with a mid-length gas port, this 5.56 AR pistol delivers smooth operation and reliability whether you're running drills at the range or building a truck gun for backcountry duty. The 16.1" barrel with 1:7 twist and CMMG ZEROED muzzle brake keeps recoil manageable and rounds on target, while the compact 6.7 lb overall weight makes it genuinely portable—crucial when you're working from tight spaces or in and out of vehicles.

What sets the Dissent apart is its thoughtful layout. The non-reciprocating side-charging handle keeps your head down and off the optic, and the reversible design works for both right and left-handed shooters. The DISSENT side-folding stock collapses to just 25.9" for serious compactness, and adjustable length of pull and cheek riser dial in comfort whether you're in body armor, a heavy jacket, or neither. The 15" proprietary M-LOK handguard gives you real estate for lights, lasers, or grips without unnecessary bulk, and the top picatinny rail plays well with standard optics mounts.

CMMG specs matter here: 7075 T6 aluminum upper and lower keep weight down without compromise, an adjustable 0.750" gas block lets you tune it to whatever ammunition you feed it, and the ZEROED trigger and safety selector are proven performers. The Cerakote Armored Black finish handles field use without whining about scratches. Two Magpul 30-round PMAGs are included, so you're ready to load up and train.

Frequently Asked Questions

What's the advantage of a non-reciprocating charging handle on this 5.56 AR pistol?

The side-charging handle doesn't cycle back and forth when you fire, so it won't interfere with your optic, rear sight, or your head position. You stay on target and maintain your grip and cheek weld. Plus, the reversible design works equally well whether you're left or right-handed.

How compact does the Dissent fold, and is it practical for truck or vehicle storage?

When the side-folding stock is collapsed, the pistol drops to 25.9" overall length—well under 27 inches. That's genuine truck-gun territory: small enough to stash in a bag, alongside a seat, or in a small safe without eating up much space. The 6.7 lb weight helps too.

Can I adjust this pistol to fit me, or is the stock position fixed?

The DISSENT side-folding stock has both adjustable length of pull and an adjustable cheek riser, so you can dial it in for your body armor, jacket, or shooting position. That dial-in capability is rare in folding stocks and worth the engineering.

What do I get in the box?

The CMMG Dissent comes with two Magpul 30-round PMAGs, so you're loaded and ready to train right away.
