Poly Choke on a Saiga (pic)

[TonyRumore 1,332]

This is the first time I have done a poly choke installation on a Saiga. It came out very nice. The Saiga barrel is so damn thick compared to most shotguns, that I was able to cut the threads directly on the barrel to screw it on. Normally, they are installed by silver soldering a threaded bushing to the barrel, but that is not required with the fatty Saiga barrel. Of course I had to true the OD with the ID first, but there was still enough meat to get it done. The barrel is 16.5" long, and the non-removable portion of the choke is 1.7" and permanently attached.

 

ACE folder, Jeric BHO, HK G3 Sights, and a Galil style charging handle polish off the package.

It's beautiful! That's the way I like my tactical guns - simple! Please leave that big magazine in it when you ship it back to me! Now If I could just get a magwell, an automatic BHO, and some 8 or 10 round mags, I'd be one happy guy!

(I think I'm a-gonna cry! )

Really gives it that SIG 550 look.

Does the poly choke create any flash hiding qualities to it? I'm asking because it has those side vents and I don't know if that is for choking benefit or flash hiding.

[IndyArms 10,186]

I think just one small word sums that up....

 

 

WOW

I plan to talk to the folks at Poly Choke and see if I can get one that is exactly like that, but with no perpendicular slots in it. Most likely that is one of the last machining operations, so it could be pretty simple to just skip the last manufacturing step. Leave it with just a solid extension tube running out the front so I can machine slots parallel to the bore instead.....like a regular flash hider.

The Poly choke works by 'squeezing' the barrel as it is screwed on - there are slits cut parallel to the bore allowing it to decrease the diameter. All choking is done before the vents. Poly choke offers their choke with or without vents, and I've had both. I think the vents are designed like a muzzle brake, ala the old 'cutts compensator'. I believe it reduces flash and felt recoil, which would make sense, since the gases are deflected perpendicular to the bbl rather than forward. I'm sure that any arrangement of slots could be machined in to be more efficient to hide flash or act as a muzzle brake. I'm totally sold on Poly chokes, I don't know why I don't see more of them, you have an infinite choice of chokes from spreader to extra full; right there. (I find screw-in chokes to be a major pain.)

That looks great Tony. I have a few poly chokes on the way for my S-12s and S-20. Two ported ones like that for the 12 and the 20 and another 12 that's just the choke itself without the added length and ports. Now I know who to talk to if I have any trouble geting them installed on Saigas. I talked to the tech guy at polychoke and he said they have an adapter they made so they can chuck the receiver and barrel in the lathe and turn the threads without having to press the bbl out.

 

Here's one that's pretty interesting I got from a fellow member in England. He had it removed from his 24" bbl S-12. It's just like the polychoke but the ports are before the choke splines. Anyone ever seen one like this or know who makes them?

Tony:

 

How much does it increase the barrel length?

That's a nice looking saiga. Where did you get the HK sight for it? Also how did you change the retracting handle to a similar one from a galil?

 

I just got my 12K the other day. I saw a benelli muzzle break w/c uses an adaptor. Would the benelli muzzle break fit on a saiga 12K?

[IndyArms 10,186]

Cobra.... the lower two pictures show a CUTTS COMPENSATOR of the "variable choking" variety...

 

I had a standard one installed on my S12, that I traded to Wakal for the AR...

 

It was nice, as I could change out choke tubes... and it also acted as a brake. It added some length... but that was never an issue with me...

The entire poly choke assembly will add 2.75" to your barrel.

 

I made a mounting block for the rear of the top cover and welded it in place to hold the rear HK G3 sight. The G3 front sight triple frame was cut in half and welded to the gas block.

 

The Galil handle was fabricated from bar stock and TiG welded in place.

How effective do you think the Poly Choke would be on a Tromix Saiga-12 SBS?

Tony,

 

If one were to get the regular permanently installed Polychoke would that 2.75" go towards the overall length of the barrel? Also does the ventilated portion rotate as you adjust the choke or is that stationary?

 

Thanks,

Only about 1.5" of that 2.75" overall is actually permanently mounted to the barrel. The front half of it, including the slotted portion, screws in and out to adjust the choke, and can also be completely unscrewed and removed.

 

I would think the choke would work reasonably well on an SBS. I am not sure why it wouldn't, but I am certainly no shotgun choke expert by any means.

If you ever been to a skeet and trap field you will see thse on several guns and I believe that a couple of manufactures had simular models but the best know is the Cutts Co. That was purchased by Lyman. The theroy is the plastic wad will expand just enough when it passes through the expansion chamber(the one with the slots) so that the shot will seperate from the the wad cleanly as it pass through the choke. If I remember the choke part was prone to plastic build up.

I also have a external choke that is spring loaded and was made for trap guns, You set the choke by pulling on it from the muzzle and it would lock into postion. This setting I beleive is a medium choke for the 1st shot when shooting doubles then the recoil of the first shot caused the choke to reset to full choke to reach out and get the 2nd bird. But most trap shooters use O/U and the barrels are choked differantlly for the same effect.
