Looks great! but... and it's a big but - Stern Defense MOD5 M-Lok Handguards

So the first issue was the lack of the barrel nut wrench it isn't a huge deal but oh well. So once you find the correct wrench you finally get to the install and timing process. I tried every combination of shims they send and nothing would even get it close... So I just lined it up so I could test fit the gas tube. That would not clear the barrel nut even if I could time it correctly. So after a little love from file I got it all to fit correctly and torqued to spec. The handguard looks great and is great quality but the barrel nut is the worst design I have seen... I couldn't in good faith recommend this to anyone..
