This one's for all you clone builders out there. 

B5 Systems is proud to reintroduce the venerable CAR15 buttstock. Perfect for both the retro and minimalist rifle enthusiast. Faithful to the original polymer design, featuring sharp checkering, fixed sling loop, and egress channel for cleaning. Constructed from modern Mil-Spec materials.

These are for MILSPEC buffer tubes.
