I used their stripped uppers and a few of their barrels on 15 plus upper builds when they first hit the market a while back. 14 of the 15 stripped uppers required the dremmel for the take down pins to push through from the big boys lowers like: dpms, spike's, BCM, Colt etc. 2 of their barrels were not threaded straight for the brake since I noticed hits right off the bat. I called them 4 times and never recieved a call back. They did finally reply to an email in similar fashion telling me I didn't know what was up. I told him to give me a call so we could discuss it and he never would. I ended up just re-threading the barrels myself since I didn't want to deal with these guys again plus their shipping times back then make PSA's look like next day air.


I ended up making pen holders out of most of those uppers and gave them to my corporate buddies for x-mas.
