What kind of lock washer do you use to keep an A2 carry handle sight mount from loosening?
Mine loosens about 3/4 turn by the time I run through a mag no matter how tight I put it on.

These handles use a leaf-type of washer, a much thinner type than what we normally think of on a lock washer.

If you have problems, simply get a bottle of lock-tite & lock it down. Use green or blue, NOT red!!!!

Make sure to thoroughly degrease both sets of threads before applying LocTite.
