Csspecs JTS-12 10 round magazine (00:28)
I did not hit the light. The bulb is going bad from being so close to gun shots. We will have a production model of this magazine in a couple months. It is a modified Saiga-12 magazine with a different front catch and different back assembly. Sits significantly firmer in the magazine well compared to any Saiga-12 magazine.

  1. Excellent magazines! 5 Star Review

    Posted by on 19th Oct 2020

    Just received my 10-round magazines for my ak-12 jts shotgun. Haven't had a chance to use them yet but the quality look great.

  2. Excellent magazines! 5 Star Review

    Very tight fit. At first I thought I'd need to do a little filing, but after examining them per their video, all that was required was a little slap on the bottom and they locked right in. Feeding was flawless. These are as good as you've been told.

  3. Great magazine for my JTS shotgun 5 Star Review

    Posted by on 11th Sep 2020

    I bought two of these Magazines for my new JTS shotgun that only came with two 5 round Mags. These are excellent quality heavy metal and lock in tightly "with a little wiggle" same when removing. I highly recommend these if your thinking about buying one. You will not regret the purchase!! Thanks

  4. Superb magazine, lots of filing. 4 Star Review

    Posted by on 17th Aug 2020

    Really well made magazines, they are all steel and the fit and finish is super tight. In fact they are a bit to tight in my rifle, hence the 4 stars. I had to file all 3 surfaces that are shown in the video. I had to remove about a millimeter of material from the latch area and completely reshape the other two areas. This could be due in part to mine being a M12-AK T1. Perhaps the mag wells are just slightly different on the T1. Overall I'm very happy with them and would definitely recommend them despite the extra filing required.

  5. CSSpecs Makes Excellent Products 5 Star Review

    Posted by on 10th Aug 2020

    I have bought magazines from these folks for some years now. Their magazines are much better then OEM magazines by a long shot. Even their shipping container and wrapping of the magazines shows that they are proud of their magazines as well they should be as they are second to none. I have also bought a couple of M77 magazines and they are just as good. I have recommended them to many folks.

  8. Two orders one for Lynx one for JTS-M12AK 5 Star Review

    Posted by on 23rd Jul 2020

    I am extremely happy with the fit and build of these magazines. I stumbled upon CSSpec from youtube shortly after I had ordered two factory 10rd mags from JTS, they are plastic and fit sloppily/seem prone to wear. These Badboys tho' they fit snug as a bug no wiggle in my magwell I did not need to file to fit they are perfect out the package. These were around 50$ a piece money well spent considering the quality. The factory 10rds plastic mags retail at 41$. I would trust my life to these magazines in a home defense situation not those plastic ones from the factory.

  9. Best you can buy !!! AK 12 Mag 5 Star Review

    Posted by on 15th Jul 2020

    Totally well made. Bought 6, opened one just to see if it would fit or if I needed to file it some. Bingo...it fit perfectly the first time around. I'm totally impressed with the quality and fit. Rock solid mag, no wiggle nothing wrong...PERFECT. Packaging and shipping totally well done and extremely fast. I most highly recommend this company and product.
