Ar question

[Jeremycg777]

I'm installing a flash suppressor on my Ar. 15 barrel and I was wondering if I Need or if its recommended to use rocksett on the threads to lock the flash suppressor on since I will be screwing a can on to it. And if I do need to use rocksett anyone know where I can get it locally at I'm in Keller

Thanks

Haven't found rocksett locally. But you can buy ounces of it on amazon and usually next day free.

Yeah from reading online I read that it's a must. Does anyone have some they want to sell today?
