Ha! Finished build #2 tonight! Nephew is in town from college. I ordered up the rest of his parts and we slapped her together. He's got the Primary Arms red dot that was on sale this weekend. Still need to throw that on and take her out for a few rounds. Should be good to go.
Aero lower, BCM blem upper, Wilson Arms 16" 1/7 carbine, cheapo birdcage, and some no name hand guard with goofy proprietary barrel nut. Seen this at a handful of local shops and they all claimed it was their own. The shop we bought it at have a 3 letter acronym for the company, but an Internet search just led me to a listing at the shop we bought it from.
Only hit one snag. The bolt catch was super tight from the DPMS lower parts kit. Luckily I brought two of my lpk's and the catch out of the second one fit great. I couldn't even shove the first one in far enough to put the pin through....it was bad. I was worried it was the lower at first. Second one dropped in just like it should.
