F5-ACR Gen 3 Cyberarm Light Brace for B&T APC – Hosted by F5 Mfg F5-ACR Gen 3 Chassis
Lightweight Pistol Stabilizing Brace – 95.75 Grams
The F5-ACR Cyberarm Light Brace, hosted by the F5 Mfg F5-ACR Gen 3 Chassis, is the ultimate ultra-lightweight upgrade for the B&T APC platform in 9mm, 5.56 NATO, .300 Blackout, and .308. This precision-machined brace attaches seamlessly through the Gen 3 Chassis, cutting weight to just 95.75 grams (nearly half the standard Cyberarm 179.50g model) while delivering superior portability, reduced fatigue, and agile handling.
CNC-machined from solid billet 6061 aluminum with advanced Skeletonization, it maintains exceptional strength. Hosted securely by the Gen 3 Chassis—with its adjustable cheek piece, bufferless folding, and rigid lockup—it creates a perfectly balanced, integrated system for dynamic shooting and tactical use.
Why It Matters
Hosting the Cyberarm Light Brace on the F5-ACR Gen 3 Chassis dramatically reduces weight while enhancing balance and ergonomics on the B&T APC. Perfect for red dot, suppressed, or compact builds across all supported calibers.
