I used this upper assembly for my first build and it shot great.
handguard came loose, gas leaks from block
The headline says it all, really. The handguard came loose after around 500 rounds. It came with no teardown manual so i guessed how tight to tighten the screws and ended up stripping the allen head. After finally getting the screws off i discovered tons of residue from gas escaping between the gas block and gas tube. Not great for keeping carcinogens and lead residue off your hands. I'm waiting to hear from Radical Firearms to get replacement screws.
