California Compliant Rifle - CMMG BR4

Published on December 27, 2024
Duration: 33:10

This review of the CMMG BR4 Ranch Rifle highlights its California-compliant, featureless design, making it accessible in heavily restricted states. The rifle features a non-reciprocating charging handle, a crossbolt safety reminiscent of shotguns, and a pinned and welded 14.5-inch barrel. While generally shooting flat with minimal recoil due to its muzzle brake and adjustable gas system, a notable issue was a light primer strike on the first round and a tendency for the bolt to not fully seat, potentially due to cerakote application or spring break-in. Despite this, the rifle demonstrates good accuracy and shootability, making it a viable option for those seeking a compliant AR-style platform.

Quick Summary

The CMMG BR4 Ranch Rifle is a California-compliant, featureless firearm designed to bypass strict state regulations. It features a non-reciprocating charging handle, a shotgun-style crossbolt safety, and a pinned and welded 14.5-inch barrel. While generally shooting flat with minimal recoil thanks to its muzzle brake and adjustable gas block, some users have noted potential issues like light primer strikes and bolt-not-seating problems, possibly related to cerakote or break-in periods.

Key features include a non-reciprocating charging handle, a crossbolt safety similar to shotguns, an adjustable gas block for tuning performance, and a proprietary, slightly elongated lower receiver for compliance. It also comes with a muzzle brake designed to reduce recoil.

What issues were observed during the CMMG BR4 review?

A light primer strike was noted on the first round, and the bolt occasionally failed to fully seat, potentially due to cerakote application or the need for spring break-in. A loose stock was also observed, highlighting the importance of checking firearm screws.
