Bufferless DISSENT architecture: Enjoy a compact rear profile and smooth cycling while keeping the full-speed benefits of a 16.1" tube.
Mk4 AR ecosystem: Drop in your favorite AR triggers, optics, grips, and mounts to tailor the rifle exactly to your mission.
Midnight Bronze finish: Durable, low-glare coating that blends with open country and looks refined on the bench.
Soft recoil, fast feedback: Stay on glass to spot impacts and send clean follow-up shots with minimal disruption to your sight picture.

Handguard style, trigger, furniture, and muzzle device may vary by SKU/production run. Always verify the exact in-box configuration on your product or retailer label.
Feature Highlights
Free-float handguard: Promotes consistent barrel harmonics and provides generous M-LOK® space for bipods, lights, and QD sling points.
Optics-ready receiver: Perfect for LPVOs (1–10×), mid-power variables (2–12× / 3–15×), or precision optics—mount and zero with ease.
AR-style controls: Familiar manual of arms supports quick manipulation and seamless cross-training with other AR platforms.
Threaded muzzle (verify pitch): Ready for a brake, comp, or suppressor where legal.
Quality materials & coatings: CMMG machining and protective finishes support reliability across high round counts and harsh conditions.
Real-World Performance Benefits
Flatter, more predictable trajectories: High-BC .22 ARC bullets help shrink wind calls and simplify dope from 100–600+ yards (with appropriate loads).
Low fatigue training: The gentle impulse lets you run longer strings, test positions, and refine holds without punishment.
Compact OAL with full velocity: The bufferless DISSENT keeps the rear short while preserving the speed and stability of a 16.1" barrel.
Modular from day one: Build a lightweight predator rifle, a practical DMR trainer, or a dedicated steel slayer using common AR accessories.
Ideal Use Cases
Predator & varmint: Leverage flat flight paths and fast follow-ups for ethical hits (where legal).
Practical carbine/DMR training: Work wind, holds, and position transitions with minimal recoil.
Range precision: Validate ballistic data and ring steel with confidence at mid-to-long range.
Smart Setup Ideas
Optics: LPVO (1–8×/1–10×) for all-purpose flexibility; 2–12× or 3–15× for dialing and refined hold mapping.
Support gear: Compact bipod or Arca/tripod clamp; rear bag for stability on uneven terrain.
Controls & comfort: Ambi safety, upgraded trigger if desired, two-point QD sling, adjustable stock to dial length of pull.
Muzzle device: Brake or comp for sight stability; consider a suppressor where permitted (verify thread pitch).
