Hey folks,
I received a Colt AR 901.  Sweet rifle.  I am awaiting a U.S. Optics ST-10 I ordered for it.  I was thinking of putting an ADM AD-RECON-SW 30mm / 20 MOA on it.  I want to run a fixed stock on it, so I am looking at the MagPul PRS.  I realize I have to use a standard ar15 A2 fixed buffer tube, but what kind of buffer and spring can I run?  Thanks.
