The purpose of this thread is to show the stages of product development. I have been working hard for the past 2 months developing a new magazine for the M&P15-22. To the forum moderators I'm not here selling anything just providing information and pics. I know there are several vendors and product development companies on this site that are capable of engineering new products for the M&P15-22. I will only provide basic information as I do not want to give away all my secrets at least not yet.

There are currently a handfull of companies who manufacture magazines for the M&P15-22. I know everyone feels a certain way about each company in regards to quality, capacity, availability, and pricing. Those companies include the stock Smith and Wesson 25 and 15 round mags, Promag's 32 round mag, and Plinker tactical 35 round mag. Please understand I'm not in no way shape of form trying to downplay any of these companies. I respect each one of them and their hardwork to develop new products for the us. I Welcome all comments. So without further a do, I will begin with the first step.

Step #1:




I reverse engineered each part of the Stock 25 rd S&W Magazine.

What's the capacity?

I will be able to supply that information when ready. Just know everyone will be happy. Trust me

That is the kind of answer I like to hear.

Not really. It would only take minor tweaking to Lakeside Machine's existing beltfed .22LR upper to work. Too bad he is selling his company.

Note that's an upper designed specifically for belt feed. It's not a modified 15-22 upper.

Sounds good to me...

Just curious. In light of the fact that since this thread started, S&W has shut down other 3rd party manufacturers of magazines for the 15-22, I'm wondering if you should proceed? Especially since you state publicly you copied their work.

I reverse engineered the exterior of their Mag. The internals are all my design. I wish I knew about the lawsuits back in 12/12 would have saved me the headaches and money. So now I have to contact my lawyer to look into the patent to make sure I'm not infringing on S&W. I already have him looking into another patent issue I recently ran into.

If these are what I think they are I'll take 5.

Awaiting more info. As a note, S&W doesn't make 15 round mags. Their are 10 rounders and 10/25 rounders.
Looking forward to see what comes next.

I'm sorry 10 round mags I'm losing my mind. Thanks for the correction. There is also a 32 and 35 round mag by promag and plinker

my advice is the promag magizines work just like the factory mags made by magpul and i would suggest the promag 32 as my second choice the 35 round tactical plinker requires some gunsmithing they are ok but require some take off at the feeder part of the mag to get them to function properly they have to be filed down to where you can take your thumb to the back of the shell and unload the mag without your thumb slideing over top of the shell and clean the feeder part of the mag up with some steel wool inside and out then the tactical plinker will funtion out every round you send through your mp15/22 this i learned from experience of tactical plinker mags get out the file or sandpaper entirely to much plastic where you load the mag at the back location of the hull needs to stand up enough to catch the shell to send it into the chamber flawlessly.look close to compare the way the shell sits in your factory mag then adjust the tactical plinker to a perfect match to bad tactical plinker cant make this adjustment in there factory so the consumer dont have to make the repair.

Sub'd.

Keep them coming and don't forget about us Kali guys who can only have 10 round mags

What is the result you are looking for? Or is this a surprise thing and we all have to wait to find out ?

Oh no sir I haven't forgot about the Cali or New York guys. I'm just focused on a current design.

Well right now its a surprise, I will disclose information when ready. Figured folks would be interested in a thread regarding new product development.

Belt feed?

No belt feeding.

Dream on. Belt feed would take a complete redesign of the 15-22's action, including the lower.

Maybe...a hopper...dump in the rounds from a bulk pack and they just self-load into the gun!

Very creative. Who is he selling the company to?

I'm not sure if anyone has made an offer. He was shopping the idea around at the Creek.

Back on topic, I really like box mags for firearms. I'm looking forward to DT's design. Please keep us informed as much as possible.

Here is my first design of the new mag after I had all the dimensions on the stock mag. Let me know what you guys think. Please keep in mind this is not the final render

Looks like a magazine.

I tried my best to make it look like one. lol

How do you load it? Most .22 mags I've seen require the loading buttons to stop your fingers breaking.

No breaking fingers here just time to load them

Some Dooshy will invent a speeloader, O wait a minute.

Looks like a double stack mag. 50 rounds would be stellar. In any case, I would prefer a load assist tab/button.

I agree, but if he makes a successful double-stack that will be quite an accomplishment. I've never seen a successful .22 double-stack because the rims in the two stacks interfere with each other.

Probably not legal in CA but I like. I hope it works and is affordable. About 3 of those would melt the barrel.

I stand corrected. First time I have been wrong ... in the last couple of hours.

Does this gun actually exist? I haven't been able to locate one.

It looks like the Keltec .22WMR which is a double stack.

I don't think the magazine is for the pistol.... The magazine is made by Shooters Ridge for the 10/22

Great find Strobro32. The Keltec pistol is a double stacked .22 cal and the stock magazine holds 30 rounds. Talk about thinking out the box

It's going to be tough getting that curved magazine into that straight pistol grip. Maybe it's flexible plastic?

The FN5.7 is not a rimmed case so that is not a good analogy. Neither is the 10/22. You can create mag column that contains double stacked rimmed cases but you can't feed them without doing something like Ruger did and create a rotary magazine loader at the top. As far as I can remember there has never been a successful working double stacked rimmed case magazine in the history of firearms. The rim is the problem. S&W staggered the rim side of the case which is about the shortest you can make the mag. But even that requires the mag to curve.

Well Sir, You will soon witness History. Then everyone will copy my design and claim they did it first.

Both examples I posted are rimmed, double stacked mags. That particular 10/22 mag is a double stacked. Both work well. It is possible to have a staggered straight mag without a curve. Look at the HK -270 20 rd mags, Practical Solutions 20/30/40rd mags and the 40 rd. Lage/Black Dog Machine mags.

Well sir I can tell you your close and a load assist tab will not be needed. I will show you when the time is right

How much more teasing can we take?????????/

IDK maybe 30 more days or less.

Please hurry. I'm old.

Subscribed....

Very nice. Keep them coming

Chad

What about Hot Pink for the Ladies? Maybe Black cammo or Dark Earth

I will buy the hot pink ones and rock them with the new pink Magpul gear I just found out about.

I have a daughter and a wife who will enjoy shooting it, and I honestly enjoy running pink guns and totally cleaning up at shooting matches. I get it is a .22, but nothing works better when people go "Hur Hur, U R Teh GayZ!" for having a pink gun and you smoke the stage clean.

KBK

Should I tag the Mag with a slogan (Real Men use pink mags)?

Solidworks? Really? Real magazines are designed with Pro/ENGINEER...
