### Features

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.

## What Customers Say

*AI-generated insights from customer reviews*

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.
