So I have an M85 on the way and I'd like to explore the idea of suppressing it. I'm an AK noob so bear with me.

I have 556 suppressors and know that AKs are louder due to gas leakage and ejection noise, let's move past that.

Is there a name for the muzzle device they come with? Are they 14mm threads?

I'll get the threads checked but have you guys had good luck with them being concentric?

If not - is there enough barrel length to have it cut back and rethreaded?

Any other tips I need to know? I'll definitely get a stamp submitted before July

I'll leave the more detailed questions to those with experience suppressing these, but on the M85 it's the FSB/GB that's threaded, not the barrel. I believe it has 26x1.5 LH threads. They usually comes with either a thread protector or a booster fitted.

All of this is assuming you bought the pistol, not the carbine with the pinned barrel extension.

Awesome. Can you confirm its originally 26mm Left hand threads? Where did you get your adaptor?

Was rethreading an option or did you just opt for the adaptor for the cost?

I have suppressed several of my AK's, and my suggestion would be to avoid it unless you have an adjustable gas block. The grenade launcher blocks work great, I also use them to adjust cyclic rate.



This is a saiga AK101 that I have dressed up like a beryl.  It is threaded 1/2x28.  As mentioned above, since the barrel profile is so light, .30 cal AK's have to use an intermediate thread of 5/8x24, a common pitch for mini 14's and older M1A's.  The problem with adapters is the barrel lacks a proper shelf to true the brake or suppressor to, and insure a concentric path.  Many of the AK specific suppressors like the Huntertown arms have a semi conical baffle path, to account for this deviation and less than perfect alignment.  I ran into concentricity issues many times, and ended up being forced to just thread the barrels or deal with possibly grenading a can, or wildly shifting point of aim.

Back to gas blocks.  AK's (in my opinion) really aren't too loud suppressed.  I shoot them without ears just fine. The problem is gas. Oh boy,  it's freaking terrible.  Your eyeball is perfectly in line with the gas tube, all the way back through the dust cover to the spring latch port, where high pressure gas is focused for increased velocity into your eyeball and nose.  It's like a jet of smelling salts blasted in your face with every shot.  My 223 AK was a longtime trial to manhood for many a young shooter.  I milled a set screw into my saiga gas block to control the gas and effectively solve the problem.  Adding an m70 grenade launcher style gas block is also an easy fix.

Thanks for the insight.
I guess I need to read up on the M70 has block.
Do you think using a can known for minimal blowback like the SOCOM would make any difference in the M85?
