$2,260.50
The CMMG DISSENT BR3 .308 Win 16.1″ Coyote Tan combines a short-stroke piston system with an adjustable gas block for suppressed or unsuppressed use. It’s lightweight, compact, and accepts Remington 870-pattern stocks — a great choice for family shooters and new AR10 owners.
The CMMG DISSENT BR3 .308 Win 16.1″ 10+1 Coyote Tan is a compact AR10-style rifle built for shooters who want a lighter, more maneuverable .308 platform without sacrificing reliability. It uses a short-stroke gas piston system with an adjustable gas block, so you can run it suppressed or unsuppressed. The 16.1-inch barrel keeps the overall length short, and the receiver accepts Remington 870-pattern Magpul SGA stocks for a custom fit. This rifle ships with a 10+1 magazine and wears a coyote tan Cerakote finish.

Key Features
- Adjustable Gas Block — Why it matters: You can tune the gas system for suppressed or unsuppressed fire, reducing recoil and keeping the action cycling reliably.
- 16.1-inch Barrel — Why it matters: Balances maneuverability with .308 Win velocity, making it ideal for hunting, home defense, or range use without the weight of a full-length rifle.
- Full-Length Picatinny Top Rail — Why it matters: Mount optics, red dots, or night vision without needing adapters — the rail runs the length of the receiver and handguard.
- M-LOK Handguard — Why it matters: Attach lights, grips, or bipods directly to the handguard at any position along the slots, keeping your setup clean and low-profile.
- Remington 870 Stock Compatibility — Why it matters: You can swap to a Magpul SGA stock for a better length-of-pull or cheek weld, using common shotgun stocks instead of AR-specific parts.
Who It’s For
This rifle is for family shooters who want a .308 that’s easy to handle at the bench or in the field. It’s also a great fit for new AR10 owners who want a reliable, tunable platform without a lot of extra weight. If you plan to shoot suppressed, the adjustable gas block makes it simple to dial in.
Pros & Cons
- Pro: Short-stroke piston system stays cleaner than direct impingement, especially when suppressed.
- Pro: Coyote Tan finish resists corrosion and blends well in outdoor environments.
- Con: The 10-round magazine capacity may feel limiting for some shooters — aftermarket 20-rounders are available but not included.
