Common Russian Muzzle Attachments for Saiga-12/Vepr-12 Review

 

Short review of different muzzle attachments, that are used with Vepr-12/Saiga-12 and some other shotguns by Russian shooters.

 

The muzzle attachments in the review: Flash hiders (FH), Muzzle Brakes (MB), Compensators (C), Muzzle Brake-compensators (MBC), chokes & paradox (Chokes).

 

Efimov design MBC

 

The most common MBC in Russia are models based on the same idea, now well known as "Polygon Muzzle Brake-compensator", that was suggested by Russian IPSC shooter Efimov Eugeny. His device has two cambers: first one works as Muzzle Brake, second one as Compensator. Molot Chief Constructor Mr. Sergey Urzhumtsev told me that first dosen of them was made by Molot and one still used during test-shootings. Then production of Efimov design Muzzle brake-compensator was moved to "Polygon" LLC in Chelyabinsk, and became known as "Polygon MBC".

Later "Guns Tuning Laboratories" started to make their own version of MBC based Original Efimov MBC (Polygon). I talked to the owner & Technical Director of "Guns Tuning Laboratories" about their PSH-2 several years ago. Their main business is to repair Trucks engines & transmissions, making Muzzle-brakes is a kind of hobby due to the Owner has Saiga-12 and likes shooting. They told that "Polygon" design was taken for their PSH-2 but they used Computer based Math models for the Hot Gases for their design, they recalculated the volumes of the first and the second chambers, increased the "window" in the second chamber & improved the "gills" as in number as in geometry making them like nozzles. As everybody knows, nozzle are more effective then standard outlet.

The same time Eugeny Efimov improved his own design, adding a couple of gills in the first chamber, and redesigned the second one splitting it for tree compensation chambers. Here is the pic of Improved Efimov MBC with 4 chambers.

Ilyn design MBC

 

One of the best MBC on the market based Efimov MBC is GK-01, designed by Vsevolod Ilyn.

 

This Muzzle Brake-compensator does not have a completely new design, but has the most improved "Polygon MBC" design, like Russian T-34 tank is the most improved version of American Christy tank. Using his huge IPSC practice experience for his design, Ilyn used first chamber of Polygon adding 10 similar to PSH-2 MBC or Improved Efimov MBC instead of 8 on "Polygon MBC" & redesign himself the second chamber of "Polygon MBC", that now has a completely new design. He also switched from Steel, that is used for making "Polygon MBC" & "PHS MBC" to Aluminum for his GK-01.

 

Ilyn MBC GK-01 now are made in Russia in cooperation with Vsevolod Ilyn by Molot, Molot Arms, IZHMASH, and in US by CSS, as well as, NoName in China - without. Molot Arms, as well as, IZMASH use D16T Al alloy rods for making their GK-01, Molot , before making their GK-01, prepare Al D16T for production forging Aliminium pigs, as forged aluminium wheels maker do for changing a structure of metal and increasing its safety factor. Now this MBC is well known in US as "Molot GK-01 muzzle brake/ Molot brake", and in Russia as "Ilyn Muzzle Brake-compensator".

The pic of Mossberg Road Blocker MB similar to Barrett .50 MB that is used by Jerry Mickulek on his shotgun. IMHO this MB can be adapted for Vepr-12 as JP.

The pic of MB based on idea that used by Mosberg and Barrett, and modified by Russian shooters, making MBC instead of pure MB.

I wan't even aware you could buy Road Blocker MR's. I was under the impression that that only came attached to barrels. So you needed to buy the lot and remove the brake.

 

Damn Papazorro, excellent information. Wish one of the business members would start importing these. So many choices bad_smile.gif

But you don't need import JP & Road Blocker, IMHO good choice for guys who need only good MB, not MBC wink.png

Very nice collection of design information, thank you for posting.

 

Personally, i would like to see a mini GK-01 design. I like the style and concept, but I am not a competitive shooter and just can not justify hanging a chunk of metal nearly the size of an AK receiver off the end of my barrel, no matter how well it works.

Here is my custom choke adapter/muzzle brake/compensator. The MBC is based on the "Cheaply" design and was welded to Cobra 76's choke adapter. The OL is 6". The front baffle is shallower than I liked, but my machinist was limited to 1.5" diameter stock.

sure would liek to see some hard data on what is most effective on all these attachments...

 

or, unless it can just be summed up in one word, "choke"?

 

Shotgun champions and your shoulder will tell you that the most effective through the years is the GK series designed by Vsevolod Illyn. 

 

Vepr 12 All Day will feature a series of videos performing a scientific comparison of many popular brakes in the coming months. 

 

The V6 brake by Bad Boy Gunz is also extremely effective, and I have been testing the steel version and the aluminum prototype on my gun for the last couple months.  This will also be featured on my channel. 

 

I believe the answer to your question will be a dog fight between the V6 and the GK-03 for brake supremacy....
