I've been scavenging the Equipment Exchange section for a couple months now and my project is almost complete.

Upper:
RRA flat top
20" SS Wilson 1:8 barrel
White Oak float tube under A2 grip

Lower:
RRA
NM trigger
M4 stock with cheek rest
Magpul MIAD grip

I have an RRA tactical carry handle on the way.  Once that gets here, I can actually start shooting the gun, knowing what I'm going to hit.  I also have a cheap 3-9x40mm tasco scope I may toss on if I can't wait.

I just got the lower from Adco.  I think I caught them in an advertising mistake and effectively got the NM trigger for free, but they followed through and shipped it as advertised.  Not many businesses are this trustworthy anymore.

I'm grinning from ear to ear
