The L&S Arcbtblk 7075 T6 Ms Buffer Tube is a mil-spec buffer tube built from 7075 T6 aluminum—a material choice that delivers serious strength-to-weight for AR platform builds. Whether you're assembling a competition rifle, setting up a duty gun, or fine-tuning a hunting AR, a quality buffer tube is the foundation that houses your buffer and spring, affects recoil impulse, and directly influences how your rifle cycles. This Lead & Steel tube is designed to mil-spec standards, meaning it'll work with standard stocks, grips, and other common AR furniture without compatibility headaches.
7075 T6 aluminum is aircraft-grade material—harder and more durable than standard aluminum—so this tube can handle the cycling demands of high-round-count shooting without deformation. The black finish offers practical corrosion resistance and a clean look that fits any build aesthetic. If you're doing an upper-receiver swap, troubleshooting a reliability issue, or building from a bare lower, having a solid mil-spec buffer tube in your parts bin is smart planning.
Lead & Steel keeps their designs straightforward and functional. There's no marketing fluff here—just a no-nonsense component engineered to spec and built to last through thousands of rounds.

Yes. The L&S buffer tube is built to mil-spec standards, which means it's designed to work with any mil-spec compatible stock, grip, and buffer assembly without modification or fitting.
7075 T6 is aircraft-grade aluminum alloy in a heat-treated condition. It offers higher strength and hardness compared to standard aluminum, making it more resistant to deformation under the cyclic stress of rifle operation.
The buffer tube is the hollow tube that slides over the receiver extension and houses the recoil spring and buffer. It's a critical part of the AR's recoil system and also serves as the attachment point for your stock.
