Big Crush Washer?
I just got one of Denny's 12.5" barrels. It came with a crush washer and A2 FH. By chance I also got a bunch of parts in from RRA at the same time, including stuff I needed for the build, a crush washer and A2 FH. I didn't know that the barrel was going to come with the washer and FH.
Anyway, I can't remember which crushwasher and FH I sent to my local builder. I got my build back and the washer was not on right. There was more showing on the bottom than the top. It looked lop-sided and goofy. So, I loosened the A2 to try and realign the washer. The washer would not go on right. It seemed awfully big, so I went and got my other one. The crush washer on the rifle was much bigger than the spare crush washer that I had. I looked at my factory LMT 10.5, and it had the small crush washer, too.
Now, the A2 came off with barely a twist. When I put the new small crush washer on it took some elbow grease on the last full turn to get it on. DId I do anythong wriong? Can you overtighten an A2 FH and Crush washer? I can't remember if this monster crush washer was included from Denny's or not.
Anyway, It looks good now. Just like my LMT 10.5"
Have Fun, Be Safe
