Product Description


These magazines are based in part on our Saiga-12 and Vepr-12 magazines.

Designed for the best possible function and firm lock up with your JTS-M12 AK shotgun.

These are not compatible with either the Saiga-12 or Vepr-12 as they have been optimized for the JTS-M12 AK for best reliability. 

This magazine does NOT fit the JTS-M12 AR.

We are working on a magazine for that firearm.


10 round magazine with all steel construction with Nitride treated surface for corrosion resistance.

This surface treatment is currently being used as a substitute for industrial hard chroming.

  1. Works 4 Star Review

    Posted by on 3rd Oct 2019

    Did not jam. That's an important criteria for any semi auto.

  2. Good Product 4 Star Review

    Posted by on 24th Aug 2019

    I bought 2 clips and they fitted perfect. I ran them through the gun twice each before i had to stop with shoulder tenderness which had nothing to do with the clips.

  3. They work Great! 5 Star Review

  4. Jts 10 round mag 4 Star Review

    Posted by on 17th Apr 2019

    Just bought my first of many great mag fits tight loads well. All in all a good buy

  5. Excellent magazines! 5 Star Review

    Posted by on 1st Apr 2019

    I have bought 4 of these magazines. Excellent quality. I had to a tiny amount of fitting on all 4, but that was no problem. Just followed Csspecs instructions. Will definitly buy more and recommend these mags to anyone who has a JTS-M12AK shotgun. These mags are worth every penny!

  6. These are amazing mags! 5 Star Review

    Posted by on 28th Mar 2019

    It's nice when you buy something and it actually performs like it's supposed to. I used them the first time I was able to get to the range. Easy to load. Rock solid. When you push that mag up there and lock it in, it feels like you just docked your shuttle with the ISS. If you run out of ammo just take one of these out and start bashing the bad guys with it.

  7. Great JTS-M12 AK Shotgun Mag 5 Star Review

    Posted by on 13th Mar 2019

    Best 10 round Mag around. Solid lock-up in gun. No fitting required in my case, just snapped in. Mag is made of steel and fed all shells with no problems. Don't waste your time with a Saiga Mag that wobbles around and barely stays in the gun.

  8. JTS M12 Ak mags 5 Star Review

    Posted by on 10th Dec 2018

    Ive bought 2 of the 10 round jts m12 ak magazines both fit and function perfectly. Great Mags.

  9. No room for improvement ! 5 Star Review

    Posted by on 5th Dec 2018

    I bought 2 of these some months back and just got 2 more. (On Sale) I have no issues with them. They hold 3 inch magnum #4 buck shot for my JTS 12. Coyote Killers. Really good fit. No issues. For anyone having problems inserting the clip. Lock the bolt open first.

  10. Great function 5 Star Review

    Posted by on 12th Nov 2018

    The design on the clip is pretty great , I had a hard time getting it to lock into the mag chamber but other then that it worked fantastic and didn’t cause any jamming issues. Definitely will not be going back to the 5 round standard mags haha
