Brownells, in collaboration with BCM, introduces the exclusive Enhanced Lightweight barrel Assembly Kits, designed for firearm enthusiasts. Available in 14.5 inches and 16.1 inches lengths, these kits feature a mid-length gas system for reliable performance. The Enhanced Profile offers a continuous taper, improving weight distribution, balance and performance, while eliminating the sharp handguard cap shoulder for better barrel harmonics and accuracy. The tapered front profile enhances maneuverability, ideal for dynamic shooting. Each kit includes a phosphate-finished, steel .625 inches BCM low-profile Gas Block and a BCM mid-length gas tube for seamless installation. Brownells and BCM combine precision engineering with practical functionality, setting a new standard in firearm performance.
