I bought a RRA stripped lower, a RRA lower parts kit, and RRA Car stock. All went together great, no problems except with the selector detent, but if you follow the directions on this site, and check the holes for burrs, you wont have any problems. (The selector detent hole was the ONE I didn't check) I HIGHLY reccommed Steve at ADCO, good prices and service. I have been very happy with them. I also reccommend Eagle Firearms. I bought some SA80 30rd mags from them, good mags and quick service. In fact I was at one of my local gun shows yesterday, and they had the same SA80 mags from anywhere from $5 to $10 more apiece! Also Eagle is running a sale on their stripped RRA lowers, $80! Thats an awesome price! As much as I've been promoting em here, I ought to buy stock!
Anyway good luck, and have fun!
