The CMMG Endeavor 100 MK4 is a semi-automatic modern sporting rifle chambered in 6mm ARC, with a 20-inch barrel and 10+1 capacity. It weighs 7.10 lbs and ships new in box with a black hard coat anodized finish.
The action is semi-automatic, so follow-up shots are fast without manually cycling. The muzzle carries an A2 compensator that reduces recoil and muzzle rise during rapid fire. The rifle ships optic-ready with no iron sights — mount whatever glass fits your purpose.
The receiver is 7075 T6 aluminum with a black hard coat anodized finish: light, strong, and corrosion-resistant. The 416 stainless steel barrel gets a black nitride treatment for hardness and heat resistance during sustained shooting sessions.

The CMMG Endeavor 100 MK4 in 6mm ARC draws mostly positive feedback, with a few recurring practical concerns.
Shooters praise the build quality and the ergonomics — the lightweight frame holds up over long sessions. The 6mm ARC cartridge gets a lot of credit for its balance of long-range accuracy and modest recoil, and owners report reliable function across a range of ammunition types.
The two main criticisms: the price is on the higher end compared to competing ARs, and 6mm ARC parts and accessories are harder to find than more common calibers, which limits customization options.
