MAC Fixed Beam Pistol Brace

Aluminum Beam Pistol Brace for Picatinny-Mounted PCCs

Whether you're outfitting a MAC IX, upgrading an MP5-pattern firearm, or configuring another Picatinny-equipped PCC, this beam-style brace delivers an ideal balance of strength, weight savings, and adaptability. Precision-machined from 6061-T6 aluminum and finished with a durable hard-anodized coating, the skeletonized beam design removes excess material while maintaining structural integrity — delivering the rigidity serious shooters demand without unnecessary bulk. At the rear, the ambidextrous tailhook-style brace repositions easily for left- or right-handed shooters by loosening the 3mm mounting hardware, flipping the brace body, and securing it in the preferred orientation. Installation is straightforward: remove the cross-tension Allen screw, slide the brace onto the firearm's rear Picatinny rail adapter, then reinstall and snug using a 3mm Allen wrench (not included). A hardened steel sliding clamp insert distributes clamping force evenly across the rail for exceptional retention without damaging the mounting surface.
