Default Loose Flash Suppressor

Hi All:

After every few rounds I find the flash suppressor to be loose. No matter how tightly I turn it back, it soon becomes loose again. I am thinking of Locktight Blue, but do not know if the heat will make that ineffective. Any one else have this issue?

Is there a missing lock washer of some sort?
Check the specifications for parts and see if it is listed ?
What make and model is it on?

You need to properly tighten it by using the proper tools. Tacticool22 sells the barrel clamp to use. If you do not use it or do not clamp the barrel when tightening the fs, you will cause damage to the bolt rails.and possibly the upper receiver.

Put some clear nail polish on the threads when you put it back on. Same idea as Locktite, cheaper and easier to remove if you need to. That's what I did and even with my QD suppressor going on and off it is still tight a year later.
