Design and key features
The CMMG MK4 Endeavor arrives in a distinctive burnt bronze finish and a 20″ barrel that is tuned for long-range precision while remaining controllable in semi-auto format. The package includes one 10-round magazine and an adjustable stock, allowing users to tailor length of pull for optics, body armor, or transport configurations. As a used unit described in excellent condition, it represents a balance of performance and value at the listed price of $1,599.99.
Ballistics and practical applications
Chambered in 6mm ARC, the platform emphasizes flat trajectory, efficient ballistic coefficients, and reduced wind drift compared with some intermediate cartridges. For defensive precision or longer-range engagement where follow-up speed and minimal recoil are priorities, the 6mm ARC delivers an effective combination of terminal performance and shooter-friendly recoil impulse. The 20″ barrel length maximizes velocity potential for the caliber while retaining a rifle profile suitable for precision semi-auto work.
