I have a #9 Harris bipod adapter for sale. This bipod adapter works with flat bottomed stocks. I had bought it for use with my Bell and Carlson tactical stock, and then I installed a picatinny rail on the forend. So I need a different adapter lol. This is practically brand new, I never shot the rifle with it on. It is still in the OEM packaging with all the paperwork. I'd like to get $20 shipped. Normally they're about $26 + shipping.
