BCM Gunfighter MCMR M-LOK Free-Float Handguard

Description

The BCM Gunfighter MCMR is a modular, free-float handguard designed for AR-platform rifles. It uses BCM’s patented mounting approach with a mechanical index to the 12:00 rail to position hardware and mitigate heat-induced movement. Precision-machined from 6061-T6 aluminum and finished with a hard coat anodize, the MCMR pairs lightweight construction with a steel barrel nut for stable lockup under sustained use. The rail accepts M-LOK accessories and is made to work with pistol-length, carbine-length, or mid-length gas systems when used with a low-profile gas block.
