I realize it is not set up as an A2 and more of an M4, but to each their own. I have an H&R formally Nodak Spud M16A2 lower. It has an Aero LPK with H2 buffer, B5 furnitureall around, Larue Trigger and BCM ambi saftey. A very nice lower that I put together for a dedicated .22lr set up. Very few rounds on it. Slap your favorite upper on and off you go. Looking for $350 cash. Or possibly trade for a threaded barrel .22lr rifle. Located in Leander. Text is best 210-3two8-one88four and
