"I built two lowers using DPMS kits and Spikes Tactical lowers. The uppers mated tightly to the lower receivers but the supplied magazine will not go in. It will go into my .223 Bushmaster lower without a problem. C-Products 6.8 SPC magazines solved the problem. The gun has excellent accuracy with consistent MOA capability."

"I didn't hope for much because of the price. My expectations were spectacularly exceeded. Fit's the mil-spec lower nicely. I added a single stage CMC trigger to the lower and now I don't want to shoot any other rifle. To say I'm pleased is understatement."

"AWESOME!!!!! Didn't expect much for the price- boy was I wrong. I was expecting a bushmaster mishap or reject when I got my 6.8 upper... it was sent from bushmaster factory to CTD- dang and got here to AZ in 4 days; that's why I only shop cheaper than dirt. AWESOME site, thanks again for delivering quality and price that nobody can come close to....."
