Non-Dimpled Barrel Gas Block Installation 2019

Yes, the torch is your friend when it comes to removing loctited screws.

This is especially true when removing a muzzle device that somebody "secured" with red loctite.

Which loctite is recommended for GB set screws?

Which loctite is recommended for GB set screws?

I've always used red for gas block set screws. I don't think any other kind can withstand the heat.

Blue and Red general purposes have the same heat tolerance but different holding strengths. There are high temp and ultra high temp variants of both holding strengths. Unless you’re mag dumping, regular loctite (red) should be fine (360 F).

Rocksett works as well. It’s designed to withstand high temps but is as hard to remove as red loctite

I use Rocksett.

Loctite 272 (high temp red - up to 450F)

That's not completely true. Rocksett has far less breakaway torque. The problem most people experience with either product is application amount and surface prep. However, the specs don't lie.

Thanks for the correction- I mistyped and meant to say that Rocksett is NOT very difficult to remove. Ive never had a muzzle device come loose when using it.

Do you guys use a torque screwdriver on the GB set screws or just an Allen wrench? If a torque screwdriver, what torque setting?

[tehpwnag3]

Others might, I do not use a torque screwdriver. I just clean/prep the threads on both the screws and GB, apply a TINY DOT of Rocksett (or Loctite) to the threads of the screws and snug down finger tight. I do let the wrench tail slightly bend a little but never to the point that it's going to snap, barber pole twist, or strip the head. Just "snug tight". That way it's not going to move under fire but I'll be able to remove them if I need to, and sometimes it is not an easy thing to do.

I'd like to hear what others do as this is just the way I do it.
