View Full Version : Most Practical Muzzle Device for 12" AK?

Hey guys!

I am in the process of picking up a Draco AK Pistol to convert into an SBR.

I would normally shy away from a CAI product but they seem to really only import these so I don't think they monkey them up too bad.

The plan is for an Ace folder when the stamp comes back. Other than that I plan to add an Ultimak gas tube and probably a KVAR black poly lower handguard, ERGO Classic AK grip, and change out the muzzle nut for a better option.

Given the 12.5" barrel length, I expect the blast to be pretty pronounced. I'd like your thoughts on what would be the most practical muzzle device for this setup? It uses standard AK threads.

Thanks for your suggestions!

If you haven't already committed to the Draco, you should look into an Arsenal SLR-107UR.

Or for an AK-105 type rifle, the SLR-107CR.

OR, the SA M-7 SFK, though it's not yet in production and will probably be more expensive.

You want a booster/flash hider.

The booster isn't needed on the Draco; it uses the AIMR/AMD65 length gas system and seems to work pretty well without it; unlike the shorter Krink length gas system.

I'd really like a 107UR, but I'm not gonna drop $1400 or more if I can find one, to then have to chop the barrel etc. If they'd do an SGL series with the shorter barrel I'd be on it.

As to the booster/flash hider these were what I originally had in mind. Honestly I don't know the differences in the two you have posted though. I'm still pretty new to AK's. Where would one be better than the other? If the Bulgy "Beer Can" would help mitigate some flash and direct concussion down range this may be the direction I go. I run a standard A2 on my Mk18 AR build with no issues and thought of maybe going with an A2 style device for this AK.

Any other suggestions?

Thanks!

$10-20 "AK" threaded A1, A2 or 3prong

$20-30: "phantom", "cage"

$50 "phoenix"

The next jump in performance would be a Vortex, BE Meyers, or AAC Blackout IVO $100

I have not comparatively tested any of the above against each-other in an AK. I extrapolate from M4 usage the vortex/meyers/blackout are more effective. However I did not want to increase OAL much... and it came out of my pocket. A $9 gunshow A1 clone now rides on a 12" Ak I use, much improved over having no device.

Both the Bulgarian cone and the "Krink" device are muzzle boosters: they provide longer dwell time (more pressure for longer) to cycle the action on a short rifle. Any other effect is secondary. The "Krink" device is a one piece thing that screws onto the barrel (or actually the front of the front sight/gas block) and has an expansion chamber to collect gas before letting it out the muzzle. The Bulgarian cone is a 4-piece device that has an inner cone, an outer cone, a spring wire, and an outer ring that screws on holding it together. They both do the same thing, just in different ways. They both use 24 mm threads.

The Draco has 14 mm threads, so you'd need to figure out something before you could use them. Personally, on a Draco, I'd go with a little birdcage flash hider. It'd be cheap, effective and keep the weapon short, with no work needed. If you spend more time learning about AKs and decide you want something different in the future, you could do the extra work to switch out the gas block/front sight with a different one with a 24 mm thread, or you could get a coupler from 14 mm to 24 mm to put on another device.

I'm not sure how well they work - but I have always thought a P90 hider would look awesome on a Draco.

Primary Weapons Systems FSC-47. Hands down.

Had a bulgy 4 piece, way too heavy and long. FSC has all the flash suppression and none of the weight/length.

Would the FSC have significant muzzle blast?

I do like the idea of keeping the rifle short and light.

I ran the FSC on my Draco. Shooting on indoor range, against the wall muzzle blast was not a problem with hearing protection and certainly not much worse than my 9mm. Now touching off a round from my AMD-65 gets me nasty looks and pretty much silences the range.

Are there any recommended A2 style flash suppressors? I've seen Krebs, Tapco, and Vulcan.


Dano, what 12" AK are you running and how does it run? I'd be interested to see some pics of your setup if you have any and would care to elaborate on what you have and why.

Thanks for everyones help so far!

When clean and lubed a Krink will run just fine without it's booster - do as you will.

Not sure about A2, but there are a number of 922(r) compliant A1 style birdcages. They work pretty well at cutting the concussion on a short barreled AK.

I would stay far FAR away from anything made by Vulcan (and Hesse, and Blackthorn, and any other name those #%!&ers have hidden behind). Tapco's 14x1 LH A1 birdcage is actually good to go. Check Cope's Distributing... sometimes you can get 'em for under ten bucks!

Thanks! I didn't realize it was the same Vulcan.
