Good stuff

Used to secure a. Muzzle brake. A lot better than the red or blue stuff consistency wise. Took off into the threads instead of sitting there to spread like some others.

Better than Loctite

I have used this to install muzzle brakes and flash hiders to be used in conjunction with suppressors on rifles. This stuff is superior to Loctite in giving me a stable and rock solid mount that allows me to move a suppressor around to different rifles without fear of the mount coming loose.

Used on Ops Inc Brake and Collar

What can I say, Follow the instructions and have your muzzle device shims already calculated and test fit before you use it and make sure your threads are 100% clean. It works and works well. I have no complaints and will use it again.

You will never use blue loctite again.

I've had the same bottle for 5 years and I still have 80% of it left. I use it for everything gun related and on the motorcycles too. After 5 years it shows no sign of drying out in the bottle. I've recommended this product to everyone I know and they all love it. It breaks with the same torque as blue loctite and it doesn't have a dye in it.

Best threadlocker...ever!

Two drops on a degreased dry thread and it's set! -350 to 2K degrees. If you value your kit, use this thread locking compound. It is actually recommended by many suppressor companies to lock on flash hiders, compensators and other muzzle devices to mount the suppressor!

Best way to secure muzzle devices

Excellent way to keep muzzle devices secure. I strongly advise against using Rocksett on small screws (such as gas block set screws) though unless you're sure it's a permanent installation. I have been unable to remove set screws secured by Rocksett, even after a long water soak and 2 hour boiling water soak. The parts in question rusted and the Rocksett never budged.
