CMMG Resolute Mk4 .300 Blackout Bronze AR-15 Pattern Semi-Auto Rifle

Description

Product Overview

The CMMG Resolute Mk4 is a compact AR-15 pattern semi-automatic rifle chambered in .300 Blackout, built around a 14.5 in barrel and a pinned and welded ZEROED SVD Brake that brings the barrel assembly length to 16.1 in. It’s designed to deliver .300 Blackout performance in a shorter overall package, with compatibility across a wide range of supersonic and subsonic loads for close-range use through longer engagements. The EML 15 handguard offers M-LOK mounting at multiple positions for accessories while keeping weight down.
