CMMG ENDEAVOR® – .22 ARC – 20" Barrel – Model 28B3D0CMB – UPC 810148627423

Stretch your effective range with a purpose-built precision AR. The CMMG ENDEAVOR® .22 ARC (20") is engineered for shooters who want long, flat trajectories, excellent wind performance, and match-leaning accuracy in a refined, optics-ready platform. Chambered in the efficient .22 ARC cartridge and configured with a 20-inch barrel for optimal velocity, Model 28B3D0CMB (UPC 810148627423) is a natural fit for predator and varmint control, PRS-style gas gun matches, and data-driven range days where consistency matters as much as comfort.

Why Choose the ENDEAVOR in .22 ARC

• Longer barrel, higher velocity: The 20" tube helps realize the .22 ARC’s ballistic potential—flatter flight, less drift, and cleaner dope at distance.

• Match-minded configuration: ENDEAVOR builds typically emphasize precision with free-float handguards, rigid receivers, and components selected for stability and repeatability.

• .22 ARC advantage: Designed around modern, high-BC bullets, .22 ARC holds speed and bucks wind better than many legacy small-caliber options—ideal for ethical predator shots (where legal) and mid- to long-range steel.

• Low recoil, high feedback: Softer impulse lets you stay on glass, spot trace and splash, and send quick, accurate follow-ups.

• AR modularity: Drop in your favorite trigger, mount your glass, and tailor furniture and controls—no special ecosystem required.

Key Identifiers

• Platform: CMMG ENDEAVOR®

• Caliber: .22 ARC

• Barrel Length: 20 inches

• Model Number: 28B3D0CMB

• UPC: 810148627423

Exact handguard profile, trigger, muzzle device, finish color, and small parts may vary by SKU/production lot. Always confirm the in-box configuration on your product label.

Feature Highlights

• Free-float handguard: Preserves barrel harmonics and provides ample M-LOK® real estate for bipods, bags, and QD sling points.

• Optics-ready receiver: Ready for LPVOs, mid-power variables (2–12× / 3–15×), or precision scopes—use standard AR mounts and rings.

• Threaded muzzle (verify pitch): Add a brake/comp for sight stability or a suppressor where legal.

• Precision-oriented build: Rigid receiver set and quality coatings/machining support consistent accuracy across long strings.

• AR-style controls: Familiar manual of arms for seamless cross-training and fast manipulation.

Performance You’ll Notice

• Flatter trajectories & fewer wind surprises: With suitable loads, the 20" .22 ARC setup reduces holdover and windage drift from 100 to 700+ yards (load/conditions dependent).

• Long-range consistency: The extended dwell/velocity window can tighten vertical dispersion and make ballistic solutions more repeatable.

• Comfort over volume: Low recoil encourages more reps—great for developing positional fundamentals and dialing in holds.

• Data-driven readiness: Stable configuration makes gathering and trusting your dope easier, whether you dial or hold.

Ideal Use Cases

• Predator & varmint: Efficient, flat-shooting cartridge with excellent downrange manners (observe local hunting laws).

• Gas-gun matches & training: Build wind-reading and position transitions without punishing recoil.

• Range precision work: Validate ballistic calculators, confirm nodes, and ring steel with confidence at distance.

Smart Setup & Accessory Ideas

• Optics:

  • All-around: 1–10× LPVO for near-to-far versatility.

  • Precision-leaning: 2–12× / 3–15× or similar for dialing, detailed holds, and improved mirage reading.

• Support: Lightweight bipod (cant/tilt), Arca or tripod clamp, rear bag for prone and field positions.

• Controls & comfort: Ambi safety, enhanced trigger (as desired), two-point QD sling, adjustable stock/cheek for consistent eye alignment.

• Muzzle device: Brake/comp to maintain sight picture; consider suppressor use where legal (confirm thread pitch on your unit).
