I'm selling my extremely lightly used SB15 brace and extended buffer tube. It comes with everything shown in the picture. That's the buffer, spring, castle nut, SB15, the original SB15 box with paperwork still inside, and the extended length buffer tube.
The SB15 is permanantly attached to the tube with black weatherstrip adhesive. I did this to keep the brace from rotating on the tube during use. It's a very clean job and doesn't affect it visually or functionally.
All sales final. No returns. I can accept PayPal by gift or if you cover the fees. First I'll take it gets it. $75.00 shipped
