Loctite 272 50ml

Loctite 272 is the threadlocker to be used when a screw must remain firmly in place and there’s no intention of ever removing it.

In the AR-15 and similar platforms, Loctite 272 is used to secure muzzle devices, especially if they’re to be used as suppressor hosts.

We strongly discourage using Loctite 272 on other weapon screws like the castle nut of the buffer tube.

Loctite 272 is an extremely powerful adhesive intended to permanently secure screws. If you wish to unscrew a part secured with Loctite 272, it will be necessary to use a blow torch on the area to get it very hot, and then apply a very large amount of torque to unscrew. Depending on the type of thread and screw, this might break it.
