Spike's Tactical SPKSLA500R-K Buffer Tube Assembly – AR-15 Rifle

The Spike's Tactical Buffer Tube Assembly provides a complete, mil-spec foundation for installing fixed or adjustable rifle-length stocks on AR-15 pattern rifles. Manufactured to proper dimensional tolerances, this assembly ensures reliable cycling and proper alignment between the buffer system and bolt carrier group. The rifle-length tube offers extended length of pull options compared to carbine configurations, making it suitable for precision shooting and hunting applications where a longer stock position is preferred.

This complete assembly includes the buffer tube, castle nut, and end plate for straightforward installation. The mil-spec diameter tube is compatible with standard AR-15 rifle stocks and buffer systems. Constructed from aluminum with a durable finish, the assembly is designed to withstand repeated use while maintaining proper buffer travel. Installation requires a castle nut wrench and basic armorer's tools.
