CMMG ENDEAVOR® – .22 ARC – 20" Barrel – Model 28B3D0CTI – UPC 810148627447
Push your effective range with a precision-minded AR built around the ultra-efficient .22 ARC cartridge. The CMMG ENDEAVOR® .22 ARC (20") is tuned for long, flat trajectories and forgiving wind calls, pairing a 20-inch barrel with an optics-ready, free-float architecture that rewards careful zeroing and consistent fundamentals. Whether you’re calling predators, stacking groups on paper, or running a gas-gun match, Model 28B3D0CTI (UPC 810148627447) delivers the velocity, stability, and repeatability serious shooters demand.
Why Choose the ENDEAVOR in .22 ARC
Ballistic advantage: .22 ARC is engineered for high-BC bullets that hold velocity and buck wind, simplifying dope and reducing drift at practical long-range distances.
20" barrel for velocity & consistency: The extended tube helps tighten vertical dispersion and improve downrange energy while maintaining excellent balance.
Free-float precision build: A rigid receiver/handguard interface isolates the barrel from sling and bipod pressure to protect harmonics and point of impact.
AR modularity: Use the triggers, mounts, optics, and accessories you already trust—no proprietary ecosystem required.
Low recoil, high feedback: Softer impulse helps you stay on glass, spot splash, and send fast, accurate follow-ups.
Key Identifiers
Platform: CMMG ENDEAVOR®
Caliber: .22 ARC
Barrel Length: 20 inches
Model Number: 28B3D0CTI
UPC: 810148627447
Exact handguard profile, trigger, furniture, finish color, and muzzle device may vary by SKU/production run. Always verify the in-box configuration on your product label.
Feature Highlights
Free-float M-LOK® handguard: Generous accessory space for bipods, QD sling cups, and positional shooting aids, while preserving barrel harmonics.
Optics-ready receiver: Mount an LPVO, mid-power variable (2–12× / 3–15×), or precision scope with standard AR rings and mounts.
Threaded muzzle (verify pitch): Ready for a brake/comp to stabilize the sight picture, or a suppressor where legal.
Quality materials & machining: CMMG’s fit and finish support reliability and accuracy across high round counts and adverse weather.
Ergonomic AR controls: Familiar manual of arms for rapid manipulation and seamless cross-training.
Performance You’ll Notice
Flatter trajectories & fewer wind surprises: With suitable high-BC loads, the 20" .22 ARC setup reduces holdover and drift from 100–700+ yards (load and conditions dependent).
Consistent dope, consistent hits: Extended dwell and velocity help make ballistic solutions more repeatable across temperature swings and elevation changes.
Comfort over volume: Low recoil encourages more reps, so you can refine position work, wind calls, and trigger control without fatigue.
Data-driven confidence: The ENDEAVOR’s stable platform makes it easier to gather, trust, and reuse your ballistic data.
Ideal Use Cases
Predator & varmint hunting: Ethical shot placement with flat flight paths and quick follow-ups (observe local laws).
PRS-style gas-gun training: Build positional skills and wind-reading without punishing recoil.
Range precision: Zero meticulously, confirm your trajectory, and ring steel at distance with authority.
Smart Setup & Accessory Ideas
Optics:
Support gear: Lightweight bipod with cant, Arca/tripod clamp, and a compact rear bag for prone and field positions.
Controls & comfort: Ambi safety, enhanced trigger (as desired), adjustable stock/cheek for repeatable eye alignment, and a two-point QD sling.
Muzzle device: Brake/comp for sight stability; consider a suppressor where permitted (confirm thread pitch on your specific unit).
