Removing a muzzle brake

[mongoosesnipe]

Should be left loosey as ar ar typical right handed threads, typical torque spec for a thread on barrel assessory is 35ft/lbs but if it was a factory installed item I would expect some sort of thread sealant was applied and you will probably need to apply some heat, if it takes more than say 45ft/lbs to break loose it is probably loo titled on and you will need heat, red lock tite breaks down at around 400*f if that doesn't get it to loosen at under 40ft/lbs take it to a smith

Also you zero is going to change so you will need to revert and you will probably want some sort of thread protector of muzzle device to protect the thread/crown
