Carbine-length CMMG Resolute Mk4 AR-platform rifle with a 16.10-inch threaded barrel, EML 15 M-LOK handguard, RIPSTOCK, muzzle brake, and optic-ready upper.
The CMMG Resolute Mk4 is a carbine-length AR-platform rifle engineered for extended-target work and hunting where a compact AR chassis is preferred. It ships optic-ready with a threaded 16.10-inch barrel fitted with a muzzle brake and includes CMMG’s RIPSTOCK and ZEROED parts. The EML 15 handguard provides M-LOK attachment points at 3, 6 and 9 o’clock plus a reduced top section for lighter weight while retaining accessory mounting options. A practical optic pairing under $1,000 for this platform is the Vortex Strike Eagle 1-6×24, which balances close-range target acquisition with capability for extended precision support.

This Resolute Mk4 blends the portability of a carbine with features tailored for accurate, longer-range performance in a compact AR platform. The combination of a threaded 16.10-inch barrel, EML 15 handguard, and RIPSTOCK gives shooters modularity for optics and accessories while keeping weight manageable for field use. The rifle is well-suited to precision-oriented target work and hunting scenarios where a lighter AR-style rifle is preferred, and its optic-ready upper allows straightforward installation of red dots, low-power variable optics, or magnified scopes for the intended application.
