Fit and function, fit and function. Not a fan of curved mags unless originally designed by the rifle manufacturer which the M14 wasn't for a reason, reliability in combat.

You are going to have a hard time proving they are as good or better than CMI to current users. Hard to teach old dogs new tricks.

So you are going to need an edge to entice users to even try.

Cheaper? Only if at least equal.

Better? Will take time to prove and if your first run has issues you can forget it.

Availability? Next shortage presents opportunity if better or equal quality.

Hard road to go...

This. Other parts possibly as well. Maybe focus on true USGI spec followers, that is a needed item. C.M.I. really does have the market cornered but a few choice parts could make you guys some money I think.

USSF06..... Have you seen "Thermold Magazines" made in the USA. Bought two from sportsman guide.....fitment is outstanding, I like them, they feel good, light weight, but I can not speek about function as I have not been on a date with them as yet. Google them, see what you think.

Give them a date at the range and report back on functionality. I work for Sportsman's Guide so would like to hear about function and reliability issues.

I have one Thermold. Fit and function is great. I haven't had a problem with it yet. Other than price. And I don't care for how it looks. If they were 10$ or 12$ they would be great. But at around 15$ I would rather get the T57 magazines from keepshooting.com for 1$ more.

I notice comments so far range from people not willing to use anything but original military M-14 magazines, to people running literally the cheapest M-14 magazines on the market... So there seems to be a wide range of views on this subject.

I assume not everyone is interested in a better functioning 30 round magazine. But it is likely that enough people likely exist to consume everything I can make and a little more.

I have some renders of the base item, these are not completely perfect because we model the tooling not the product, so these are made using the tooling as a sort of sinking tool in cad.

There is supposed to be a front cap that will act as a gusset for the front of the magazine and will transfer load into a larger section of the magazine while thickening the front and side in a high stress area.

The feed lips are heavily corrugated, I make a couple types of magazines with this style of feed lip and they perform well in drop tests, they are significantly harder to bend. Generally having a stiffer feed lip gives a magazine a significantly longer functional life.

The volume of holes in the sides is optional, one top and bottom is needed for accurate forming. The holes are spaced every five rounds and are offset on one side to give an accurate reading regardless of side viewed.

The shoulder support rib is further to the back of the magazine to allow for reliable function with shorter projectiles.

Follower is shorter to prevent front to back binding, the case shoulder rib is used as the forward stop.. The two indents at the front top area engage with a pair of tabs on the follower, by grabbing lower we can reduce the inclination to roll when engaging the bolt stop.. This should make activating the bolts stop significantly more reliable.

Floor plate will have an internal retaining plate to prevent crushing and will prevent swelling, a take down button will be in the center to allow magazine to be disassembled without any tools. Follower and spring can be pulled straight out and push straight in without any twisting.

I hope you didn't take my comments as too negative. As a business owner in multiple industries I was expressing my concerns on marketing. If you make a better mag and can survive the initial marketing you will succeed.

Looks pretty cool by the way.

From a business standpoint I still would think that there were easier markets to capture. As an example doublestack handgun magazines that are in short supply, easier, cheaper to manufacture and sell for double. Just my two cents....

I would try one as well. My preference would be to eliminate as many of the holes in the side of the magazine if possible.

Here are some thougts for additional consideration:

Aside from the long mags being ITW (in the way) for some shooting positions, the weight, mass, and moment arm must be considered.

How does this all respond to recoil? Having that much low mass will certainly effect rise, rythem, and return to target. Espcially on the first few rounds when it is heaviest.

Here's a test: attach something securly of equal additional weight equally that low as the proposed larger mag to an existing 20 rounder. Go shooting and see if you like it. Maybe it will be a positive surprise. Maybe is will just frustrate your range time. Don't know yet.

And how will the additional mass under recoil treat the mag well in general? Will having a heavy item down there reacting to each shot be not good for the gun in the long run? Don't know that either.

A bad effect may not show up after 200 rounds. But how about after 2000?

And dang, how hot do your want your barrel? 30 rounds? Things already sizzle with 20 rounds!

Just musing FWIW. No one is bad.

Loading a 20 rd magazine can be a PITA that's why I use a Upula M14/M1A mag loader. Using it on a 30 round curved magazine could be a challenge. Plus the longer mag would hinder bench rest shooting, but if it functioned flawlessly and easy to load could be an asset when needed.

They might consider 25 rounds instead of 30.

Looks good would try them out the holes may allow debris to get in the magazine and cause issues though
