LBE H3 Buffer Tube Kit for AR-15

LBE H3 Buffer Tube Kit

This complete buffer tube assembly provides everything needed to build or upgrade the rear receiver extension on your AR-15 platform rifle.

What's Included

• Six-position mil-spec diameter buffer tube
• Carbine length recoil spring
• Receiver end plate
• Castle nut
• H3 heavy recoil buffer

Performance and Design

The H3 buffer is engineered for shooters who run suppressed rifles, short-barreled uppers, or heavy ammunition loads. Its increased mass reduces bolt carrier velocity and provides smoother cycling with less felt recoil impulse.

LBE manufactures these components to precise tolerances, ensuring reliable function and long service life. The mil-spec diameter tube fits standard AR-15 stocks and components, making this kit compatible with most modern AR platforms.

Why This Matters

A quality buffer system is fundamental to reliable AR-15 operation. Mismatched or worn components lead to feeding failures and increased wear on critical parts. This complete kit eliminates guesswork and provides a proven solution for shooters who demand dependable performance.
