Spike's Tactical SLA500R 6-Position Buffer Tube – AR-15/M4

The Spike's Tactical 6-position buffer tube provides a mil-spec foundation for adjustable stock installations on AR-15 and M4-pattern rifles. Machined to military specifications, this buffer tube ensures reliable stock adjustment and consistent lockup across all six positions, supporting improved shooter fit and control during target transitions or positional shooting.

Constructed from 7075-T6 aluminum with a black anodized finish, this buffer tube features standard mil-spec threading (1.14x16 TPI) and accepts mil-spec carbine stocks. The unit includes drain holes to prevent moisture accumulation and includes staking notches for castle nut installation.
