If or when you get some for testing let us know.
+1 @shrub I'd say look at the Ruski 74 plum mags. Great light and work, if it is -40 or 120 degrees. But at the same time stamping and injection molding are 2 different animals.

Should mention the Russian mags have a steel rib that runs along the front of the mag body, on the bottom where the floor plate attaches, in addition to the lugs and lips.

Keep a 10 rounder of some sort in your hip pocket. It may be a niche of a niche but there are more than a few of us and CMI is a choice for me only because I have 44Mag, etc., to front their products. They won't sell direct to me anymore and have blacklisted my state. Their website won't even open.

Their website opens just fine for me. And I'm a nobody I guess that's why.

I'm not sure how cost effective it would be. CMI primarily does progressive stamping, which is basically a huge press that does one part of the operation every so many inches of travel, with the magazines being transferred by mechanical feeders. Basically complete parts less welding roll off the stamping machine, starting with rolled steel sheet and ending with magazines. Every stroke of the press is one magazine, normally 30-60 strokes per minute.

We primarily do hand transfer stamp work, which means people handling each part several times. We are more capable of handling bizarre shapes, and doing more complex steps, but humans cost more money per part than machines. Most of our work is very old school stuff.

When you are working with something like 10 round magazines which are straight, odds are CMI will be cheaper.. I will keep you in CA in mind, but I don't want to get anyone's hopes up that these are going to be dirt cheap..

Ditto what everyone has said about 44mag and CMI

It's not clear from the new proposed regs what methods might be acceptable to convert existing mags so there might not be a "clean" retrofit method. Probably wouldn't make sense to do as a full, different product. Some are blocked internally and then the blocking process locked in by welding, riveting or epoxy, etc.

So in our looking over of the test sample after the test firing. We noticed some scuffs on the tips of the feed lips from the bolt, it appears that the same exists on our CMI mags, and well as the other knockoffs we have samples of. Is this a common thing or do I have an odd rifle?

We also notice that the feed angle is basically parallel to the bore but lower, and that it seems to depend on the ramps cut into the receiver and barrel to get the round into the chamber, even with the ramps the projectile is getting a little scuffed, normally I don't want to see any projectile contact unless it is absolutely needed.

If we lower the back of the magazine just a little that we could improve the feed angle a little and reduce the scuffing on the feed lips.The bolt contacts the rounds with about .10" of wiggle room before we get into any potential malfunctions of the bolt riding over the back. So it is well within the design norms to drop the magazine a little. I need to see how much rise I can get out of the follower to ensure that it activates each and every time.

Does anyone have heavily used CMI or original military magazines they would be willing to sell or lend? I would like a sample with a reasonably well known volume of fired rounds to set a baseline of wear.. I'd prefer something with about 500-1000+ rounds fired and another with 2000+ fired rounds, really needs to be a 20 or 25 round that was loaded to full pretty much each time.

So tooling wrapped up some time ago. I have parts coming in to make a batch of production models.

Anyone want to volunteer to test them? I do ask that they be viewed from the standard of function rather than adherence to the 1959 milspec drawing, because this thing is different in almost every way.. We do hand transfer sheet metal work, which allows us to make more weirdly shaped items then what you can do with progressive stamping, so we added a number of features that we think will improve function.

Spot welds are a little more spread out on the sample. I did not have the coolant system hooked up so I spaced the welds a little more.

Having caught up on the thread, and since I've never shot my M1A yet, "adjusting" my shooting position won't require adjustment at all... it'll be fresh and new to me.

I'd be totally down with beta testing these, but there would be issues. We'd probably be best to discuss on PM

No reason to think you can't bring something new to a timeless platform that has merit IMO!

Me!

Nevermind my profile here... I have a home in Arizona and you could ship one there for me.

BTW, what the world REALLY needs is for somebody to make decent M1Carbine mags... Especially now that Inland is making reproductions.

Send me a couple I'll test them and return them if you want.

Well this is done and wrapped up. Figured I'd post the ending to the story.

After a few months of processing we finally got a finished batch.
Mag in the photo is a randomly selected sample out of about 1000.

Function was as expected. All 30 and locked back on empty.. Did a fair amount of shooting and took measurements, no measurable deflection.

Obviously demand is different from when we started back in early summer of 16' before the election.. But at least I probably get to make them for the next four years.. I have not seen much demand through my website, perhaps we miscalculated the market, or perhaps we are not understanding the data.. Either way I'll know more once they actually start selling.

Still waiting on parts for my E2 stock.. So I have it in a plain jane.. I have to say y'all have better "fair condition" stocks than what the AK guys get.. My last batch of "fair condition" AK stocks had be field altered with an axe or very dull bayonet and had the finish bubbling off.. The M14 stock needed a little wipe down with oil and it was good to go.. I bought three because I figured I was going to pick the best of three and repair it, now I need two more rifles to fill my nice stocks.

Uhhhh... They're not yet for sale, right? Given that there's no supply, how would you know if there's any demand?

How much are these going to cost? CMIs are going for less than $20 shipped (Brownells sale).

My website tracks incoming traffic using IP address, so I know how many people in legal states have looked. I'm seeing results that make me less confident. I have been wrong before in the other direction, the data is not perfect.

Sadly I can't even dream of touching CMIs current clearance pricing, I think some of the retailers are actually selling below cost. We are basically double that price. Back when we started, the plan was to slip in around the retail cost of the sold out 25 round which was about $43.. So that is the price point we built to.. These are hand transfer stampings from laser cut parts and pretty much manually built.. Just because someone dropped their pricing the cost of manufacture did not change.

The M14 parts market only really started tanking in the last 60 days. I had already committed to the parts in January. Like most of the players in the game I have to make decisions about market conditions well before I have data to actually support them.. I think we made an excellent product, we just had bad timing.

We are scrubbing the finish residue off and putting the parts through gauges, should have the first mags in bags around lunch time tomorrow.
