Built on BCM BCM4 receivers, this pistol uses 7075-T6 aluminum with a hard-coat anodized finish. The upper shows BCM branding and includes an ejection port cover, forward assist, and shell deflector. A continuous Picatinny top rail with T-marks (approximately T2-T38) provides uninterrupted mounting real estate. Receiver markings include "BCM Rifle Company - Model BCM4 - Cal MULTI," with manufacturer marked Hartland, Wisconsin, USA.
The 11.5-inch barrel uses a threaded muzzle and is fitted with the SureFire WARCOMP-556-CTN closed-tine device. A BCM MCMR-10 free-float M-LOK handguard in 6061-T6 aluminum gives ample M-LOK attachment real estate while keeping weight streamlined. An M-LOK QD sling socket is installed for quick sling placement.
Ergonomics and controls are set up for confident handling. The ambidextrous charging handle with extended bilateral latches offers easy access from either side. A flat-faced trigger shoe provides a straight press, and the B5 Systems pistol grip delivers a secure hold. The manual safety is present, and a BCM-marked bolt carrier group is installed.
Transport and storage flexibility come from the Law Tactical folding stock adapter, paired with the SB Tactical SBPDW adjustable stabilizing brace. The platform is direct impingement, semi-automatic, chambered in 5.56mm NATO, and built on the AR-15 architecture.
This micro-format BCM4 pistol ships with a 20-round Magpul PMAG, and the listed components are installed and ready for the buyer. Capacity is 20+1 with the included magazine.
