I removed my old plastic carbine length handguards to install a free float handguard assembly.
Using a DPMS armorer's wrench, I removed the barrel, and later reinstalled it just guessing how many ft lbs of torque i was applying.
I've come to realize that I may have overtorqued it, and have noticed that since I've re-installed the barrel, recoil is significantly heavier. Another thing, i've had quite a few feed problems since I did this as well. I'm going to remove the barrel today and THIS time, use a torque wrench to tighten the barrel nut.
Any ideas on this, overtightening the barrel nut causing heavier recoil due to tighter headspace??? Maybe tighter bolt/lug lockup also, making the bolt unlocking a lot harder than it should be?
