CMMG Dissent Mk4 300 Blackout 6.5" 30+1 Semi-Auto Pistol - Tungsten Gray

The CMMG Dissent Mk4 is a compact AR-style pistol chambered in 300 Blackout and built around CMMG's signature bufferless operating system. The result is a remarkably short, maneuverable personal-defense weapon with an overall length of just 14.70" and a weight of only 4.60 lbs.

At its core is a 6.50" barrel optimized for the .300 Blackout cartridge, paired with a semi-auto action that cycles through a compact bolt carrier group without a traditional buffer tube. The pistol offers a 30+1 round capacity, making it a feature-rich, ready-to-run platform right out of the box.

The upper receiver, lower receiver, and barrel are all finished in a rugged Tungsten Gray Cerakote for corrosion resistance and a clean, modern look. An optic-ready top rail allows direct mounting of red dots or low-power variables, and ambidextrous safety controls make the pistol equally comfortable for left- and right-handed shooters. A factory-installed Zeroed Drop-In Single Stage Trigger provides a clean, consistent break out of the box, while the included OEM grip in black polymer keeps the profile slim and ergonomic.

A Picatinny buffer adapter at the rear offers added mounting options for pistol braces or accessories, letting the user configure the pistol to suit their preferred setup. Manufactured in the USA by CMMG, the Dissent Mk4 packs serious 300 Blackout performance into a compact, feature-rich, ready-to-run pistol platform.
