This is our functional and popular billet lower together with our new billet upper. This is not our side charging upper, and is designed to work with standard ejection port and forward assist assemblies. Machined from aircraft quality billet aluminum, this combo offers a rigid design that rivals the top names on the market and a much lower price point. Features like a threaded bolt catch allow for seamless lower assembly without scratching the finish. The tension screw removes any ‘slop’ between upper/lower fitment. Hard coat anodized TOGETHER for a lifetime of work. The ‘Integrity’ of this combo is not easy to pass up.
