CMMG DISSENT — .22 ARC, 16.10" Barrel (28B940CHCA | UPC 810148627539)

Meet the next-gen small-bore that hits way above its class. The CMMG DISSENT .22 ARC (16.10") brings the DISSENT platform’s modern ergonomics and precision build to Hornady’s flat-shooting .22 ARC cartridge—purpose-built for long-range varmint, predator, and crossover target work from an AR-15–length package. With a full 16.10" barrel to maximize velocity and a lightweight, free-floating forend for accessory mounting, this DISSENT configuration delivers fast handling, outstanding downrange ballistics, and the feature set serious shooters expect from CMMG.

Why Shooters Want the DISSENT in .22 ARC

• .22 ARC performance: High-BC .224 bullets with excellent retained velocity and wind resistance—ideal for predators, varmints, and practical rifle training at distance.

• 16.10" accuracy build: The “do-most” barrel length for .22 ARC gives you meaningful velocity gains, flatter trajectory, and predictable DOPE without a bulky profile.

• DISSENT handling, AR familiarity: Modern controls, modularity, and a free-float handguard with M-LOK® slots for lights, bipods, tripods, and sling QD points.

• Optics-ready: Flat-top receiver for effortless scope or LPVO mounting; pair with a 20–30 MOA mount for more elevation if you stretch past mid-range.

• Tuned reliability: Quality barrel/bolt fitment and CMMG’s attention to gas/port timing (platform-dependent) support consistent cycling across seasonal temps and round counts.

• Purpose-built precision: The DISSENT chassis and free-floating forend help keep the harmonics stable for repeatable groups from prone, bags, tripod saddles, or barricades.

Key Specifications

• Capacity: Compatible with AR-pattern .22 ARC/6.5 Grendel/6mm ARC-type magazines (verify your magazine’s follower/geometry for .22 ARC)

• Item/Part #: 28B940CHCA

• UPC: 810148627539

• Intended Use: Predator/varmint, prairie dogs/coyotes, steel/target, property and ranch rifle, training

Compatibility Note: The .22 ARC typically uses a 6.5 Grendel/6mm ARC bolt face and corresponding mags. For best results, use quality magazines labeled for these families and confirm reliable feeding with your chosen ammo.

Field & Range Advantages

• Flatter flight, better wind calls: Compared to traditional .223 loads, .22 ARC’s high-BC bullets hold velocity and buck wind more effectively for cleaner hits at extended ranges.

• Manageable recoil: Stay on glass and spot impacts—great for calling corrections solo, teaching new shooters, and making fast follow-ups on wary coyotes.

• Accessory-friendly forend: Add a lightweight bipod, ARCA adapter, or barricade stop without affecting barrel harmonics.

• Balanced for position shooting: The 16.10" configuration points quickly for offhand shots yet settles naturally on sticks, packs, or tripods.

Set It Up Right (Pro Tips)

1. Optic pairing: A 2-10x, 3-15x, or compact LPVO with reliable tracking makes the most of .22 ARC. Consider a cantilever or canted base if you plan to dial past 600+ yards.

2. Ammo testing: Try several bullet weights (e.g., 62–75+ gr high-BC) to find your node. Chronograph to build true DOPE for your density altitude.

3. Mag selection: Use reputable Grendel/ARC-pattern magazines; mark mags dedicated to .22 ARC to avoid mix-ups.

4. Support gear: A lightweight bipod, sling with QD points, and a rear bag or tripod saddle will maximize positional stability without adding bulk.

5. Torque & witness marks: Proper base/ring torque and marked screws help you maintain zero through transport and high-round-count sessions.

Who It’s For

• Predator & varmint hunters who want flatter trajectories and better wind performance from an AR-length platform.

• Crossover competitors/trainers practicing holds and wind calls with low recoil and high barrel life.

• Ranch & property owners looking for a precise, quick-handling rifle for pests and long shots across open country.

• Ballistics tinkerers who appreciate the .22 ARC’s modern bullet options and efficient case design.

Care & Maintenance

• Routine cleaning: Keep the BCG, gas path (platform-dependent), and chamber clean; lightly lube bearing surfaces for smooth cycling.

• Barrel care: Use a bore guide and non-aggressive solvent; avoid over-cleaning once the barrel is settled into a node.

• Hardware checks: Verify handguard, optic, and muzzle device torque after travel or extended strings.
