OK so today I took my stock barrel off and re-installed it.
I have a shop with a bench and nice vice but I am losing it. I have read multiple horror stories about how hard it was to removed the factory barrel. I figured while I still have the shop I will break it down so when I do replace the barrel it will come apart easier.
The barrel nut came off like nothing. I used a Magpul barrel wrench, a 1/2 breaker bar, and a Seekins action rod. I cleaned everything up, set the headspace using Manson Precision gauges, lubed it up all the threads, torqued to 75 gt lbs, and put the rest of it back together.
I took it to the range and shot some Hornady American Gunner. It was shooting 2.5 mils higher than before. I did not think it would be dead on but I did not expect that much of a difference. What do you guys think?
I’ve had a slight POI shift just by changing a hand guard. Probably due to different flex under recoil, position of the bipod, etc. As long as it’s nothing crazy and the rifle is just as accurate, I wouldn’t worry about it.
I tightened my barrel nut to 70 ft lbs and it was fine
