I just bought the upper from a friend -
it's a PSA with a Noveske barrel and an Odin works forearm, (the barrel's free-floated).
I milled the lower, and it has an American Trigger Gold trigger in it.
Magpul stock and a Primary Arms AMD red dot to top it off.
I just picked up the upper this weekend, put the red dot on it and sighted it in Sunday, I still have to put a dust cover on it. Which is going to be a slight pain in the butt, because I'm going to leave the barrel on; the procedure for a Noveske barrel is fairly tricky and since it's already been done competently, I'm leaving it alone. So, the hinge pin's going in left to right, instead of right to left; which means trying not to lose the world's tiniest c-clip.
Thinking about a muzzle-brake for it, but don't know very much about them. There's a gun show this weekend so maybe I'll see something that'll catch my eye.
UPDATED: Made it to the gunshow, found a compensator/brake, and put the dust cover on.
50 yards, benched, with the reddot you can see in pic.
