Model/SKU: 55B8D86-SG | UPC: 810097509313
Compact, fast, and feature-rich, the CMMG DISSENT in 5.56×45mm pushes the AR platform forward with a short 10.5" barrel, lightweight but rugged 7075-T6 aluminum receivers, and a slim 9.60" free-float M-LOK® handguard. Designed for modern accessories and tight-quarters handling, this DISSENT configuration gives you a rock-solid front end for lights, switches, and grips while keeping the system short, balanced, and easy to maneuver for training days, home-defense setups, or suppressed use (where legal).
Why Shooters Choose the CMMG DISSENT
Short 10.5" 5.56 performance: A proven barrel length that balances compact handling with dependable 5.56×45mm velocity and function.
Free-float 9.60" M-LOK® handguard: Real estate for white lights, hand stops, and QD sling cups—without influencing barrel harmonics or point of impact.
7075-T6 aluminum receivers: The same high-strength alloy used on premium ARs delivers stiffness and durability with excellent weight savings.
Buffer-tube-free family design: The DISSENT line eliminates the need for a traditional receiver extension, opening up compact stock/brace* options and unique rear accessory possibilities.
Optics-ready top rail: A full-length Picatinny surface makes mounting a red dot, prism, or LPVO simple and repeatable.
Clean ergonomics: AR-style controls and a comfortable grip angle support consistent manipulations under timers or low light.
*Always verify current laws and product configuration in your jurisdiction.

Muzzle Device Note: Most 5.56 barrels are threaded 1/2×28, but always confirm your barrel’s markings before installing brakes, comps, or suppressor mounts. Re-zero after any muzzle device change.
Performance You Can Feel
Control & speed: The short barrel and free-float handguard make it easy to drive the dot through fast transitions while keeping recoil flat.
Accessory flexibility: M-LOK slots and a continuous top rail let you place lights, lasers, and switches exactly where your support hand needs them.
Reliable accuracy: Rigid receiver/rail alignment and free-float barrel support repeatable groups from barricades, bags, or slings.
Setup Ideas (Day-One Ready)
Defense/EDC home rig: Enclosed-emitter red dot, compact weapon light at 1–3 o’clock, two-point QD sling, and vetted magazines.
Training/Courses: LPVO 1-6× or 1-8×, hand stop, labeled mags for reload drills, and a quality brake for a flatter impulse.
Suppressed use (where legal): Correct thread-mount device and adjustable gas (if applicable). Confirm concentricity and re-zero.
Pro Tips
Zero smart: A 50/200-yard (or 36-yard) zero keeps holds intuitive from 0–300 yards.
Witness-mark everything: Optic screws, handguard hardware, and muzzle device timing; verify torque after the first range session.
Magazine vetting: Test all mags with your chosen ammunition; replace weak springs and mark any outliers.
Run it wet: A light film of oil on the bolt, cam pin, and carrier rails boosts reliability in high round-count classes.
Who It’s For
Home & property defenders who want a compact, accessory-ready 5.56 platform.
Students & instructors taking carbine classes and shooting high round counts.
Enthusiasts building a versatile suppressed or night-capable rig (where legal) with modern light/laser placement.
Care & Maintenance
Routine cleaning: Wipe bolt face, lugs, and carrier rails; clean the chamber and bore as needed.
Hardware audit: Re-check optic/base torque and handguard screws after travel or heavy firing.
Muzzle device care: If swapping devices or running a suppressor, inspect threads, use the correct shims, and verify alignment.
Compliance & Safety
Know your laws: Magazine capacity, muzzle devices, and configuration (stocks/braces) are regulated. Confirm all local/state/federal rules.
Safety first: Follow the four rules of firearm safety and validate reliability with your chosen load before defensive use.
