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.

Thanks again Mark, I'll send ya pics of my build when it's complete. I'm currently working on a dissy.
