The JP Enhanced Carbine Buffer Tube from JP Enterprises represents a refined JP-SPEC revision of the standard Mil-spec buffer tube, delivering smoother function and longer component life with an extra stock position for a total of seven and a finer exterior finish to minimize friction against the buttstock. This 7.25 in., 3.9 oz tube is crafted from 7075-T6 aluminum and finished in hardcoat anodizing to provide durable, low-friction performance while allowing additional threading into the receiver to optimize protrusion for use with our Silent Captured Springs. It is fully Mil-spec compatible and includes a buffer tube lock ring and lock plate for secure installation. An added stock position stop and high-quality exterior finish reduce wear and feel for quieter cycling, with an internal finish refined for smoother operation and reduced wear of the buffer components. Designed to integrate seamlessly with standard components, this Black JP Enterprises buffer tube supports enhanced reliability and controllable cycling in a wide range of rifles while offering precise fitment and straightforward installation for extended shooting sessions and dependable field use.
