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.

I bought two of these mags a couple months ago. they fit nice and snug in my m1a and work without fail so far. As of now, they are nothing short of awesome.

Ordered 2 J-6 30 round magazines for M1a 11-26-2020 received them 12-01-2020.(In my world that's pretty quick these days) Unpacked wiped them down, put one straight into the weapon fit perfectly. No fitting both fit like a glove. ( to find after marked parts made this well made in todays world is rare)
Thanks Robert

Bought 3. Super impressed on design. Fast shipping. Well packaged. As other reviewer noted these fit better than gi mags! The slight curve also assists in the rock to lock in. No problem loading the full 30. Feeds great! Ok 2 small complaints. The finish on mine is uneven, almost looked rubbed off on the center; and the top rear of the follower that appears to activate the bolt stop when empty, is very sharp.
Csspecs:
Finish can be rubbed with a little oil which will make it darken again, the grain of the finish is dry which makes it reflect more looking grey. The sharper upper corner on the follower bolt stop is somewhat unavoidable, blunting the corner makes it less reliable.

Great product and quality construction

I've bought 3 of these magazines now and have loved every one of them. They feed flawlessly, fit into the rifle better than gi magazines, and are the only 30rd magazines that works for the m14. They even cost less than the magazines Springfield sells for the m1a under their own name so if you're willing to spend the money for a rebranded checkmate then do yourself a massive favor and give these a try.

Ive used your mags for years in my Zastava My so I was not surprised when the 30rd M14 worked just as well. Its the ONLY 30rd mag I found that functions 100% of the time in the M14. I wish you made 20rd ones as well because I would use them exclusively. Keep making quality products lile this and I'll be a life long customer.

unwrapped the mags and loaded them up. No jams. Flawless performance. These are heavy duty mags. Not cheap crap. Great product

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.

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.

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!!!
