Does one have to use moly or loctite when screwing on an FH during installation? 2nd, does anyone have a pic of a crush washer? I picked up one at a gunshow and I'm not sure if it's a crush or peel washer. thanks!

Crush is on the right. I did't used loctite on my A2 with peel washer, and haven't had any problems.

Thanks Mark! I indeed picked up a crush washer. I plan on using it with an a2 FH. Any tips?

I haven't done one yet, but apparently you just tighten the FH until the washer starts to compress. Stop tightening when you are indexed. I'm guessing you wouldn't have more than a full turn after the washer starts to crush.

This may sound like a dumb question, but does the wider beveled side of the washer face the FH?

It's not a dumb question at all. I don't remember. Lotboy has a Colt upper with the crush on it, and I can't remember which way it goes. I think people here have done it both ways.

Someone here will be able to tell you. I think the wide part touches the FH.

correct. also, I use blue loctite since it's temporary, but you don't neccessarily have to use it.
