The Meloniting/ Salt-Bath Nitriding (also called QPQ) process heats the barrel or bolt carrier group to 1100 degrees by dipping it into meloniting salts in liquid form.

This process and the lower temperature being used is dramatically reduced from the standard heat treatment process, giving less chance of warping the barrel, less damage to the steel.

Compared to chrome lining, the meloniting process is both a superior process and cheaper.

And talk about corrosion resistance! You could feasibly throw your barrel or bcg in ocean, come back a year later, and it will still look the same! (Please note that we did NOT just suggest that you throw your AR in the ocean).

Meloniting also gives the barrel or bcg a Rockwell hardness of between 68-72. Read: that’s stinking HARD! It’ll last longer, it’ll be easier to clean, and reduces copper fouling.

You can fire in excess of 15,000-20,000 rounds without seeing degredation in a melonited barrel. (Remember how many round we said a non-treated barrel could shoot earlier? Told you there’d be a test!)

This can double to triple the service life of the barrel. Your grandchildren will shoot out that barrel before you do!

Note: You cannot melonite a chrome-lined barrel or bcg. The chrome and melonite salts have a violent (read: explosive) reaction to each other. We’re trying to increase the life of the barrel, not shorten it!


Minute of Angle (MOA) is the term used as the standard for measuring the accuracy of a hunting rifle. You can also use minute of angle as a means of measuring the size of an animal’s target zone. In the simplest terms, there are 360 degrees in a circle, each degree has 60 minutes. The calculated distance extended to a target at 100 yards is 1.047 inches or “one-minute.” This number is just a crosshair over “one inch” and to make calculating easier, most all hunters and shooters use “one inch,” this is called “shooter’s minute of angle.” In terms of accuracy, if a hunter and his/her rifle can shoot three or five rounds and have them group inside one inch at 100 yards, then you have a minute of angle group, or a minute of angle rifle.

A muzzle brake or recoil compensator is a device connected to the muzzle of a firearm or cannon that reduces the amount of perceived recoil when the AR is fired, as well as helping to control muzzle rise after the firearm has discharged.

They are also used on pistols for practical pistol competitions, and are usually called compensators in this context.

Flash suppressors are very different from muzzle brakes! While they are both located/mounted in the same place on the AR, muzzle brake is used to reduce the perceived recoil a shooter experiences (and typically has zero to do with eliminating flash), while the flash suppressor only limits the amount of flash the shooter sees and usually does not affect recoil.
