Welcome to Bravo Company Mfg®

Enhanced Lower Parts Kits

BCM® now offers a complete lower parts kit for AR15 rifles, made entirely in the USA from components built from Mil-Spec AISI8620 investment castings, AISI8620 bar stock and using 17-7PH stainless steel springs as well as advanced manufacturing methods to insure longevity under hard use.

Including the BCM PNT™ Trigger Assembly, the Mod 3 Pistol Grip and Enhanced Polymer Trigger Guard, the BCM Lower Parts Kit is built from 100% parts machined to Mil-Spec standards with all polymer components available in Black and FDE.

Today, the commercial market is flooded with a mash up of inferior imported OEM parts with sloppy dimensions, hardness, finishes, and cheaper alloys. BCM continues to set the standard for quality American made components, that offer a long service life for those that may find themselves in harms’ way.
