For shooters looking to extend the effective range of a lightweight AR platform without stepping up to heavy calibers, the right rifle combines ballistics, balance, and modularity. The CMMG ENDEAVOR MK4 22 ARC answers that demand with components and geometry tuned for precision and repeatable long-range performance.

CMMG ENDEAVOR MK4 22 ARC

Key features that matter

Chambered in 22 ARC (Advanced Rifle Cartridge) and fitted with a 20″ barrel, this ENDEAVOR delivers near 22-250 performance from an AR15 (Mk4) weight class. The package emphasizes practical long-range shooting: a Magpul MOE rifle stock for consistent cheek weld and fit, the ZEROED drop-in trigger for a crisp break, and a ZEROED muzzle brake to manage recoil and follow-up shots.

Design and modularity

EML 15 handguard and mounting options

The EML 15 handguard gives ample real estate for M-LOK accessories at the 12, 3, 6, and 9 o’clock positions while integrated Picatinny rail sections ensure solid mounting points for optics and backup sights. That balance of slim profile and accessory options keeps weight forward where it helps on offhand and supported shots.

Ambidextrous control package

CMMG outfitted the ENDEAVOR with a comprehensive ZEROED ambi suite: 60deg/90deg ambi safety, ambi charging handle, ambi mag catch, extended mag release button, and ZEROED pistol grip and trigger guard. These controls improve handling for shooters who run bilateral positions or need rapid manipulations under stress.

Ballistics and field use

The 22 ARC cartridge provides high-velocity, flat-shooting performance ideal for varmint work, precision sport shooting, and extended-range training without the heavier recoil and logistics of larger rifle cartridges. With a standard 10rd magazine and overall length of 39.8″, the platform remains maneuverable while delivering long-range capability.
