M14 30 round magazine

  • Left side view of magazine, bottom view hole is 30 rounds.
  • Right side of magazine, the witness hole is compensated to show full at 30 rounds.
  • Top view of magazine. The follower locates off of the shoulder restriction and is shortened to reduce binding.
This magazine has been live fired hence the small scuffs.
  • Image 4
  • Comparing length with a 10 round SAI mag, a 20 round CMI mag,  a 25 round CMI mag, to a Csspecs 30 round.
Note that the additional length ratio is roughly the same as the 20 and 25 round.
  • Comparing approximate size of a 30 round Csspecs M14 mag to a 30 round AK magazine. Note that the magazine takes about the same squared area. Interestingly the M14 mag is slightly lighter.

Product Description

 We are currently out of stock, we are in the process of making more.

Should be back in stock Late November to mid December.



Many 30 round magazines for the M-14 have been made over the last 50+ years, few have been deemed reliable.

This new design not just a stretched 20 round but is made to be a true working 30 round magazine.

Corrugated stampings on the feed lips prevent deforming with the higher spring loads needed for 30 round magazine.

Front catch is reinforced with an additional layer to reinforce this critical location.

Magazine is curved after a short straight section to prevent low feeding.

Floor plate is removable without tools to allow easy cleaning.

Follower is laser cut to allow exaggerated bolt stop.

Rear contact point is fully CNC milled and conventionally spot welded rather than projection welded.

Magazine is 8.625 long and weighs 12 ounces empty.

Magazine finish is Black Nitride.

The finish is an industrial type application rather than a cosmetic finish. So the finish can and does have shading variations from one mag to another and texture differences are common.

  1. Worked fine in my SOCOM16. 4 Star Review

    Posted by on 15th May 2019

    They arrived VERY nicely packaged for long-term storage in sealed plastic with CPC paper wrapping. Build quality is very high. I only have 2 areas of concern;
    1.) When loading the mags as received the spring tension was excessive. Inserting a full mag on a closed bolt was difficult as was cycling the action to chamber the first round. 2.) I also noted after ejecting my dummy rounds that the stamping edge on the feed lips scarred the brass deeply.

    I took one of the three magazines I received and cut a coil off of the spring and filed and polished smooth the feed lips where they dug into the brass. The results were easier loading, easier chambering and brass ejected in much better condition. I could also now fit 31 rounds in the magazine. Though I would not typically make it a practice it is equivalent to the oft-recommended practice of underloading a magazine to relieve the effects of tightly packed magazines.

    I took the modded magazine and the as-delivered magazines to the range and they all functioned perfectly. The modded magazine was just easier to use. I honestly can't say it functioned any better. I wound up modding all of them but I would recommend them either way.

  2. Perfect! 5 Star Review

    Posted by on 6th May 2019

    Finally got to test these m14 30rd magazines out,and I'm extremely happy with them. Quality construction and they worked flawlessly. I would recommend to anyone who is looking for high cap mags for their rifle.

  3. Couldn't be happier!!! 5 Star Review

    Posted by on 20th Apr 2019

    Quite frankly... These are the best 30 round M1A/M14 magazines in the business!
    Springfield Armory doesn't even offer a 30 round magazine for the M1A/M14.
    I ordered six of these 30 rounders and I received them within a few days. They came packaged wrapped in grease paper and plastic bags and they were brand new!
    Got to test them several of them out today on the range and they fed flawlessly. I am very impressed and these are well worth the little extra cost. These are VERY well made magazines. The best that can be had in the M1A/M14 world. Outstanding quality and workmanship. BRAVO to CCSPECS!!!

  5. best magazines 5 Star Review

    Posted by on 10th Apr 2019

    Csspecs produces the best magazines for your 7,62 x 51. As close to the original military item, and in some cases better.
    I am very happy with them

  8. M1A Magazines 5 Star Review

    Posted by on 25th Oct 2018

    Received a great Mag and will use it whenever I want extra rounds to fire.

  9. 1st mag dump was flawless right out of the box 5 Star Review

    Posted by on 19th Jul 2018

    These mags are extremely well made and very robust. Previously, I had about a dozen or so 25 round CMI mags, (which are also great), but now, knowing how good these are, I'll be replacing my CMI's with these.

    I did a 30 round mag dump first thing with this mag (have video of it too), and every round fed properly, the last round hold open worked flawlessly as well (unlike SOME 30 round mags out there)...

    I would recommend these mags to M14 enthusiasts everywhere!

  10. Would recommend to anyone 5 Star Review
