I'm contemplating the purchase of an AK type rifle in 5.45x39 because the surplus ammo is so cheap compared to other calibers. My concern is how to sufficiently clean the pinned muzzle break. That surplus ammo is corrosive and most folks that shoot it remove the MB to really wash the corrosive salts off. How do you do it with a pinned and welded brake? Thanks.

Soak the [gun and] muzzle brake in hot soapy water, clean with some solvent to remove any carbon buildup, dry and your ready for another fun day of shooting.

Its a pain in the a$$. Soak and dry the interior of the muzzle brake with Q-tip (or something else that can fit). The opening is very small hence the pain in the A$$ part.

For corrosive ammo use windex. The ammonia neutralizes the mercuric salts. Hang the gun upside down by the buttstock. Spray the windex downt the barrel and then on the inside of the brake (assuming you're talking about the 74 style). Let it go for a bit then clean with your normal stuff.

 

I've also thought about using a baby bottle brush from the grocery store once i install my 74 brake.

I sometimes soak a 12 gauge bore brush in simple green and just scrub all around the muzzle break in and out of the shapes. It mangles the brush over time, but it doesn't matter i just switch to a new one every few times. You can also get cloth barrel bushes. Personally i don't find cleaning the muzzle break to be the hardest part of cleaning my AR-15, i have a harder time in the upper part of the inside of my receiver and with the gas pistol rod assembly.

Stand it in an old mayo glass jar with solution and let it soak...

Or use belly button lint remover...

Is that a real thing? I don't want to be laughed at in the pharmacy

Haven't checked this thread in awhile. Have any of you had any indication of those nasty salts working their way through the welds and into the threads?
