I recently had to have my Mcmillan Tac-50 muzzle brake removed and sent off to get refinished due to a deep scratch. I have got the brake back and am looking for the type of thread lock you guys would recommend me use for re-installation.

Thanks

Re: Mcmillan 50 muzzle brake help

Rocksett for all practical purposes, is permanent. In your case, it is not necessary.

Blue loctite would be fine if you wanted to be able to remove it later. Red loctite if you wanted a little more security. However, if you have a way to get a wrench on it in order to torque it, I would just do that.

+1

McM doesn't use any threadlocker on their muzzle brakes. Just clamp the barrel in a vise closest to the muzzle and use a large crescent wrench (with tape on the jaws to prevent scratches) and give the muzzle brake a good snug.

Quite the contrary, apparently.

Re: Mcmillan 50 muzzle brake help

Pin and spot weld is one of the 2 ways you can do it....
Rocksett is not permanent you can get it off by..... freezing it or soaking it in a soapy water solution for 24 hrs.

Re: Mcmillan 50 muzzle brake help

1100+ degree silver solder also appears to be an approved method as well.

ever tried putting a McM Tac50 in a barrel vise and tightening it down? I hope you have an extra set hands. I installed a AAC Cyclops break on mine and it took one to hold the barreled action in the vise and then the other had to turn the 18" wrench to torque it down.
