Chambered in 22 ARC (Advanced Rifle Cartridge), the CMMG Endeavor Mk4 Semi-Automatic Rifle, equipped with a 20" barrel delivers 22-250 performance out of the lighter weight AR15 (Mk4) platform.
Each CMMG Endeavor rifle is purpose-built for long-range performance, with everything from the Magpul MOE rifle stock to the ZEROED muzzle brake, and every part in between selected for its utility to the avid marksman.
The EML 15 handguard maximizes customization potential. M-LOK attachment slots at the 12, 3, 6, and 9 o'clock positions give you plenty of real estate to mount accessories, while the Picatinny rail sections allow for easy and solid mounting points for sights and accessories.
