CMMG 35B5FBCAB Resolute MK4 350 Legend 16.10, Armor Black, M-LOK Free-Float Handguard for AR-Platform, Upper Receiver

Overview

The CMMG RESOLUTE Mk4 Upper Group in Cerakote Armor Black is a complete, ready-to-assemble upper designed to pair with any standard AR-15 lower receiver. Chambered in .350 Legend—a fast-moving straight-walled cartridge prized by deer hunters in caliber-restriction states for its optimal downrange power and reduced recoil compared to traditional hunting rounds—this upper is optimized for intermediate-range shooting, whitetail hunting, and tactical applications. It features a 16.1-inch medium-taper 4140CM SBN barrel with a 1:16 twist, a carbine-length gas port location, a non-adjustable 0.750 gas block, and a 1/2"x28 threaded muzzle equipped with a CMMG ZEROED muzzle brake. Built upon a billet 6061-T6 aluminum upper receiver and a CMMG EML15 M-LOK free-float handguard, the assembly includes a matching bolt carrier group and a suite of CMMG ZEROED components, including an ambidextrous charging handle and a polymer dust cover.
