I did a review earlier on the "Barrel Screws" bolts.. I going to backtrack they are garbage. When I was tearing down the firearm for regular cleaning they came out alright, but upon reassembling they both stripped the threads. They are made from cheap aluminum DO NOT BUY!! and for the handguards let's get say they can't standup against simple abuse (running drills) don't drop them. There are better companies out there. Buy at your own risk.
That being said this was a budget build. The cheap parts can not standup to the punishment! I would look for more quality parts for around the same price point .. and yes there are better quality parts for the same price range. Not this inferior **** on this site.
Hope this review helps someone.
