Sorry to revive such an old thread but I got bit by ordering the stupid Brownell's 308 armorers wrench for the barrel nut on a LR-308B. >:(
Wish it would have said in the description it doesn't fit DPMS barrel nuts!
*It did say in the reviews (which I didn't read). A 308 barrel nut is a 308 barrel nut right? That's what I get for assuming. Grrrrrr...
And the right wrench is out of stock! Double Grrrrr...
Who knows how long I'll have to wait for the correct wrench to come in?
Never gonna get my build done at this rate. :'(
