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. M14 30rd mags 5 Star Review

    Posted by on 15th Mar 2018

    Very high quality

  2. Best M14 Magazine Hands Down 5 Star Review

    Posted by on 26th Nov 2017

    These mags are made of high quality materials. Magazine fits perfectly snug into my socom 16. I bought one of these to try out and absolutly 100% satisfied in quality and reliability. Just purchased 4 more of these. These mags will not disappoint and they are 30 rounders which is a plus.

  3. Almost Perfect 4 Star Review

    Posted by on 23rd Oct 2017

    I own a M1A scout rifle. This is the only 30 round mag I have ever had for the m14/m1a that will manually cycle all 30 round through the rifle with no problems. These magazines are built better that USGI spec Magazines. However, there is a slight con to these magazines (not one that will keep the mag from working) but does present a small issue. These magazines are slightly larger at the mouth of the magazine - than mil-spec USGI magazines and a current issue check mate magazines. (I have a original USGI KMT mag from 1969-1970 and current issue Check mate mag I compared it to). And with larger mouth area it makes inserting these magazines into the magwell a little tough - and will take more effort than it normally should.

    Other than that - this mag works fine. It will be a keeper. And worth the price I paid for it.

  4. Solidly built! 5 Star Review

    Posted by on 21st Sep 2017

    Just like a CMI 20 round magazine, these 30 round magazines are solid. They don't "stretch" when you fill them up like cheap magazines do. I bought two and they are both flawless. I was very skeptical because I've got another brand's 30 round mag and they were terrible, they would eject rounds with the slightest vibration and have feeding issue. Not these mags. A little expensive but I think all magazines are too expensive.

  5. Best ever 5 Star Review

    Posted by on 15th Aug 2017

    Purchased 2. Ran 60 plus through each..30-factory 30 reloads. Not a hiccup. These mags are way way better than Springfield armory puts out. Solid, reliable. I recommended to a friend, he bought 2. Same results. Will be ordering more and I commend the staff for providing such a quality product. Thanks Csspecs.

  6. Way more than I expected 5 Star Review

    Posted by on 25th May 2017

    I purchased 2 M14/M1A Mags and just got through running 90 rounds thru each. These are the most professional mags. I have used....they are solid, rugged, and detailed to fit perfectly in tour weapon. The factory mags from S/A don't come close to the quality of these Csspecs. They are the best quality mags I have seen and have proven to be absolutely reliable. I will be purchasing more. Great job Csspecs. These are the only true 30 rounders made for my rifle.
