I bought a CAR parts kit from them at a gunshow a few weeks ago to put on an EA lower.I only needed the complete upper, but the upper + BC +CH would have cost MORE separately than the whole kit, which includes a decent collapsible stock, etc. The finish is good.
The problem is that when I try to open the bolt, it get hung up in the fully open position. It will close if I loosen the pushpins or tap the butt on the floor. I'm not sure where the BC is getting hung up...maybe the buffer, but I'm not sure how to find out. Maybe I'll put on the Model 1 stock and see if that helps. Any ideas are welcome.
But the upper fits and functions just fine on a BM lower, and also the RRA lower. I'm waiting for delivery of conversion pivot pins so I can try it on one of the large hole Colts.
Anyway, the kit seems to be a decent deal for the money...not top line but not bad for a shooter. I've lurked the boards a while...you guys are a great resource.
