Optimized for heavy .224 bullets and long, efficient ogives, 22 ARC delivers outstanding wind performance and retained energy—while staying in the lightweight, accessory-rich AR-15 footprint. The ENDEAVOR build adds a free-float handguard, precision barrel, and match-friendly ergonomics so you can stretch distance on coyotes, prairie dogs, and steel with confidence. *Color/finish conventions vary by run; this model’s “CCT” designation denotes a tan Cerakote finish. Why Choose 22 ARC in the ENDEAVOR Platform Long-range .224 ballistics: Designed around heavy 75–88+ grain bullets, 22 ARC provides flatter trajectories and less wind drift than legacy .223 loads—without big-frame recoil. AR-15 handling, big results: Keep familiar controls, lighter weight, and broad parts compatibility while reaching distances you’d expect from larger cartridges. Proven feed system: Uses a Grendel/ARC-style bolt face and runs best in 6.5 Grendel-pattern magazines for reliable cycling with long COAL bullets. 20" velocity sweet spot: The extended tube boosts MV and consistency, making dope collection and hit percentage easier at range.

What Sets the ENDEAVOR Apart Free-float accuracy: The handguard isolates support pressure from the barrel for consistent POI off bags, bipods, and barricades. Purposeful ergonomics: Extended sight radius, adjustable stock, and ambi-friendly controls help you run the rifle efficiently from prone to tripod. Optics-ready real estate: Continuous top rail for LPVOs or mid/high-magnification scopes, with room for clip-ons and offset red dots. Cerakote durability: Coyote Tan finish is tough, weather-resistant, and blends naturally in open country. Ideal Use Cases Predator & Varmint: High-BC .224 bullets anchor coyotes and stretch small targets with precision and low recoil. Practical Precision Training: Practice wind calls/position changes on a gas gun that tracks like your match rifle. Ranch & Field: Lighter than big-frame ARs, with the reach to manage pests across fencelines and pastures. Suppressor-Friendly: Tame blast and spot impacts more easily with compatible .22-cal cans (confirm rating and thread). Setup Tips for Best Results Magazines: Choose quality 6.5 Grendel-pattern mags—they feed 22 ARC’s case geometry and long OAL bullets more reliably. Glass: A 2-12x, 3-15x, or 4-16x FFP scope with a usable wind tree and dependable tracking pairs perfectly. Support Gear: Add an ARCA plate to your handguard for tripod work; run a cant-adjustable bipod for prone. Ammo Selection: Test several 75–88+ gr loads; 22 ARC shines with heavy bullets for BC and wind deflection. Gas/Buffer Tuning: If you switch to a suppressor or different muzzle device, fine-tune gas and buffers for smooth ejection and minimal dot movement. Maintenance & Ownership Break-in & Clean: Follow CMMG’s guidance; keep the gas system and chamber clean for consistent groups. Fastener Discipline: Verify torque on optic mounts and M-LOK hardware; add blue threadlocker where appropriate. Data Tracking: Record MV, DA, and wind with each lot; 22 ARC responds well to clean dope across seasons.
