The Advanced Technology A5101050 Commercial Buffer Tube Assembly is a direct-impingement system component built for AR-15 platforms that demand durability and reliability. This commercial-grade buffer tube is machined from 6061-T6 aluminum and finished in black anodize, a battle-tested combination that handles the cycling forces of repeated fire while resisting corrosion in the field. Whether you're building a new rifle, upgrading an existing platform, or replacing a worn tube, this assembly gives you a proven foundation for your lower receiver and stock system.
Advanced Technology specializes in no-nonsense components that work—no marketing hype, just solid engineering. This buffer tube is designed to standard commercial dimensions, making it compatible with the broad ecosystem of AR-15 aftermarket furniture and stocks already in circulation. The 6061-T6 aluminum alloy delivers the stiffness and impact resistance you need for duty-grade reliability without unnecessary weight.
If you're assembling an AR-15 from scratch or refreshing the internals of an existing rifle, a quality buffer tube is non-negotiable. This one handles the job without breaking the bank, letting you invest your money in optics, triggers, or barrel upgrades where it moves the needle on performance.

Frequently Asked Questions
