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. Almost perfect 5 Star Review

    Posted by on 7th Apr 2018

    I am well pleased with the construction of the magazine. After filing it down is sat in my JTS perfectly. I had one jam the first time i shot it, but I havent had another problem since. I would love it if they came out with like a 20rd drum!! Will be buying more

  2. Nice n tight, 5 Star Review

    Posted by on 2nd Apr 2018

    Fits perfect and spring is strong. What else do you need except a multi-pak discount?

  3. Almost perfect 4 Star Review

    Posted by on 2nd Apr 2018

    I purchased two of the 10 rounds magazines and they are really nice but the way they lock in place is a little iffy, you have to wiggle it past the opening then lock it in but it does function well with all 10 shells firing and ejecting so if the top was maybe a little smaller it would be perfect. Let me know if you change anything I would love to try them out

  4. Great fit 5 Star Review

    Posted by on 30th Mar 2018

    Took it out of the packaging straight to the gun. Fit perfectly. Not sure why some had to modify the mag. Mine clicked in and came out great. Bought 2! I have yet to fire it, but I'll let you know how it cane out later.

  5. Very pleased 5 Star Review

    Posted by on 28th Mar 2018

    Alot more fun than the 5 round mags. Very pleased with all steel construction. And I plan on getting more soon

  6. 2 more 10 rd mags 5 Star Review

    Posted by on 28th Mar 2018

    Got 2 more of the 10 rd mags from CSSPECS (non blems) this time.
    These things continue to impress me.
    Wish they were a little cheaper. But, the performance is there so far.
    4 of the 10 rd mags are sure a lot more enjoyable at the range than 4 of the 5 rd mags.

  7. Took some work, but it fits now 5 Star Review

    Posted by on 27th Mar 2018

    Received the mag and packaging was exceptional. Very sturdy build. Checked fitment and it was obvious I was in for some filing. Had to work on the back of the mag where the mag catch seats.Went slowly since you cant add any back if you go too far. Finally fond the sweet spot and mag locks up properly. A shame the factory cant keep the specs on this shotgun a little tighter. It is Chinese however, so not unexpected. Mag works great. Thanks

  8. Works great! 5 Star Review

    Posted by on 19th Mar 2018

    The fit was perfect! Works great!

  9. 10 rd mags work 5 Star Review

    Posted by on 18th Mar 2018

    Takes a little time getting used to inserting the mags properly.
    But, let me to tell you - these things flat out run! I ran 200 rds first time out with my JTS with 5 rd mags (4 of them).
    1 week later went out and ran another 170 rds of Winchester super x with the 10 rd mags (2 of them) that I bought from CSSPECS. Sweet Jesus is that a lot more fun.
    And I got the last 2 blem mags they had. Thanks CSSPECS!
