Jam Nut, Black Nitride .223/5.56 - 1/2X28

If you have the time & patience or your muzzle device, doesn't have to be timed in a certain position, crusher washers & shims work great. I personally hate installing Crush Washers. Jam Nuts are the easy way to get everything perfect on the first try. It also doesn't hurt to use a little heat resistant thread locker, when using this item.

Would of given it 5 stars but they only included 1 in the package instead of 2 when I ordered.

If you have a Muzzle Device that needs to be Timed, this & some heat resistant thread lock is what you need, to avoid the headaches of shimming your muzzle brake. So much faster & easier.

It is so fast to time a muzzle brake. Get it close and tighten down. Was so much faster than spacers. Got 4 the new upper was great without having to use one. Will use one on the 223 long rifle wit the compensator.

What can I say, it's a nut that holds your muzzle device on. And that's exactly what it does, and it does it really good!

Does exactly what it should do

Works

I like the speed this part was delivered and quality if it.

Bought a barrel nut and compensator. Fast shipping. Recieved the products i ordered. Look to be good reliable products. Havent installed yet. Will update after install.
