For marksmen who demand long-range performance without the weight of a traditional rifle, modern cartridge engineering and modular AR platforms have closed the gap. The result is a rifle that offers .22-250 class ballistics in a lighter, more maneuverable package suited for precision work, varmint control, and competitive target shooting.

CMMG ENDEAVOR MK4 22 ARC

Key features and ballistics

Chambered in 22 ARC (Advanced Rifle Cartridge), the ENDEAVOR MK4 22 ARC uses a 20″ barrel to deliver 22-250 performance from a lighter AR15 (Mk4) platform. That combination produces a flat trajectory and reduced recoil compared to larger centerfire options, making it ideal for extended strings of fire and follow-up shots during varminting or long-range precision practice. The rifle ships with one 10rd magazine and an overall length of 39.8″.

Purpose-built components

This ENDEAVOR comes configured with a Magpul MOE rifle stock for ergonomic adjustability and a ZEROED drop-in trigger to sharpen shot-to-shot consistency. The platform includes a ZEROED muzzle brake to help manage felt recoil, plus ZEROED pistol grip and ZEROED trigger guard for a matched control feel. Ambidextrous controls are robust: ZEROED 60deg/90deg ambi safety, ZEROED ambi charging handle, ZEROED ambi mag catch, and ZEROED extended mag release button streamline operation for left- and right-handed shooters.

Customization and on-gun utility

The EML 15 handguard maximizes customization potential with M-LOK mounting slots at the 12, 3, 6, and 9 o’clock positions, giving ample real estate for lights, bipods, and grips. Picatinny rail sections provide secure attachment points for optics and backup sights. The ZEROED AR15 bolt catch and ZEROED AR15 polymer dust cover complete a ready-to-use platform that requires minimal aftermarket modification for serious shooters.

Why this rifle stands out

The CMMG ENDEAVOR MK4 22 ARC is notable for translating high-velocity varmint cartridge performance into a light, familiar AR chassis while packing purpose-selected components—Magpul MOE stock, ZEROED controls, and an EML 15 handguard—right from the factory. Whether you’re finishing a long-range cull, dialing in loads on the range, or building a precision training rifle, this configuration offers a ready, configurable solution.
