Greetings, I'm sure this has been discussed before but I'll ask it anyway. I'm going to install a 20" barrel on an AR-15 A1 upper. It's been a lot of years since I've installed a barrel. I've watched the Brownells video, they say keep it close to 30 ftlbs then I read one post where 90 ftlbs was mentioned . When I was in the Navy and was replacing worn out Vietnam era M-16 barrels we torqued the new ones to 70 ftlbs + or - per NAVSEA. I have 1 AR-15A1 I built back in the late 80's and torqued it to 70 ftlbs as I did in the Navy . I've put a LOT of rounds thru it with no issues at all. Now I'm just old and confused LOL... So what IS the correct torque ??? ANY help most appreciated !!
