Product Description
The SBA H2 Receiver Extension Kit includes our SBA H2 Spring, Mil-Spec Buffer tube, and steel castle nut & end plate. The SBA H2 Spring is a drop-in buffer system designed to help the AR-15 platform function more smoothly and quieter. The H2 style buffer weight system is an all-in-one system with higher tension and more reciprocating mass than the standard SBA. It is easy to install and quickly reduces friction and vibration with much smoother harmonics than traditional buffer systems. Fits M4-style buffer tubes for AR-15 semi-automatic rifles.The buffer tube has been hard coat anodized for maximum corrosion and wear resistance and the steel castle nut and end plate are all thats required for installation. This assembly kit will fit on all Mil-Spec AR 15 lower receivers
