AR15 PISTOL BUFFER TUBE
Rock River Arms AR15 Pistol Buffer Tube
Knurled section at the front
This buffer tube has a slightly larger diameter than most pistol buffer tubes making it a very good / tight fit for the SB15 Sig brace as you can position the brace further back on the tube without it sliding forward.
