I had to send my 15-22 back for the OOB I sent in the mag according the instructions. I got the 15-22 back and took it out yesterday for a trial run. Rounds 1-150 were perfect. Between rounds 150- 400, I had 9 FTL where the round gets stuck vertically in the mag. After being ready to send it back, I noticed that one of my four mags didn't have a problem. I started looking them over and noticed that the one with out a problem also said "22 LR" with "25 Round" underneath.

picture 1 is the old mag on the right and the new on the left.


I looked over the new different mags and didn't see anything different and just figured it was to differentiate between the 25 round and the new pinned 10 round. So I continued to shoot the rest of what I had and between rounds 400-500. I had 1 more FTL, but never with the new mag. Shot 125 rounds and no more problems, I think it may finally be breaking in.

After shooting I looked closer at the mags and noticed the new mag was slightly different than the old ones. not by much but I think it might help. If you look at the two mags below the new one is on the left and the old on is on the right. If you look at the orange slider from the front, you can see about four millimeters on the old one and three on the new one. The difference is in the black housing of the mag. In the new one it sticks up further. Picture 2


This causes the bullet to be slightly angled upwards when the round leaves the mag compared to the old mag which is more horizontal.

Over the years I have used and tested many different magazines for 1911s, most issues I have run across with that style of gun that were feed issued can be traced to magazines.
Better presentation from magazine to chamber is one of the best ways to improve feeding, along with proper spring tension.
I have also had luck with tweaking the feed lips, not sure if that is possible with that magazine material however.
Hopefully this change will be across the board in all the future mags.

Maybe I missed it but was the mag that worked returned to you with the rifle?

sorry I guess i should have been more clear

When I sent my gun back I included the mag that was in the gun during the OOB. When I got the gun back it had this new mag included and not the old one.
 
Ah ok, well hopefully that will be my fix, I just sent mine back yesterday for the same problem. Thanks for the info.

Uh, oh, I bought three new magazines within the past month. All were the old style. :(

Same here, if it turns out that S&W has tracked the problem to the mags then I feel like everyone who has the old mags should be able to send them in and get the new mags. Just sayin' cause I spent hard earned dollars for this outfit.
 
Studying those photos, I can definitely see a pronounced inward and higher design on that new mag. The other photo I can see the bullet in a more upward stance for feeding.

Definately a design change. Cost wise it would kill S&W to replace everyones mags I understand. BUT, the question remains was this the problem S&W found which means the 4 mags I have are defective ?

Guess I'll wait till it blows up in my face to find out.
 
what would it take to put a little epoxy on the old mags in order to get the bullet to be slightly angled more upward?

anyway, until we have reports from many more sources that the "new" mags are working better, we shouldn't jump to conclusions. i'm glad that mag worked great for rip3000gt but he's the only one we heard from so far.

having said that, it seems plausible that the mag was one of the main culprits all along. i'll have to check the 2 new mags i ordered from smith two weeks ago.
 
I know the pictures are not the best and yes it is hard to see the difference because it is minimal, I forgot to post in the original message that the distance between the top of the orange slider and the bottom of the groove in the black housing is 3mm for the new and 4 mm for the old, not a lot of difference but some.

I don't believe this will solve the OOB but does help with the Failure To Load, the Failure to Eject was solved by changing the placement of the ejector.

The OOBs still need to be solved because either way the shells should not be crushed by the bolt to the point of setting of the round.

I have no idea if the new mag that I got was an intentional change in the mag or what but I do hope we hear from others than can confirm that there was a change.
 
OLD STYLE MAGS

I've got eight of the "old" style mags, per description above. My FTF problems have occurred when I've been careless loading the mags. I check for staggered offset in the mag and the top round nose high as it protrudes from the top of the mag. I've only run about 3-400 rounds thru this "early" serial number so far. Mostly FTF issues, only a couple FTE.
Like some of the other members, I'm concerned that the FTF issues relate to the magazines. Someone's bound to offer an improved, aftermarket magazine for these great little carbines.
In the mean time, I will continue to painstakingly load each one very, very carefully. It's a wonderful thing when you can blow through 25 rounds rapid-fire mode without a FTF.
I'm new to this site and appreciate all the input people are offering on this model!
Thanks,
Bill
 
I would like to add that I always make sure that the rounds are loaded perfectly so that would not attribute to the old mags having failures to load
 
The pair of complementary magazines I received with my repaired MP15-22 on Christmas Eve were "old style."

My guess would be a simple mod to the follower and the angle/height of it. That would be an easy part to order and change out if in fact there is a change?

From August-Dec 2009 Smith & Wesson didn't want the magazines sent in with the rifle. They were sending repaired rifles out and adding two more mags with them but they were the same old type mags.

I for one think it's about time they make parts for this gun available for order. I've seen nothing so far being offered.
 
It looks the same to me. Plus the angle of the mags looks skewed to me. The red guide is only going to be on the first bullet and by the time you stack 20+ rounds the angle looks like it will be the same. if the bullet was inserted all the way and not just laying on top it would be a better comparison.

picture quality is bad yes, the one mag is slightly at an angle yes, but there is a difference

in the picture with the bullet, the bullet is in the mag but pushed out just to the point of coming out. It does not matter if the bullet has the follower or other bullets underneath it because it is being held in that position by the black housing.
 
I hope this is the fix for those who have a problem. So far I've not had one issue with mine and I think it has to do with making sure the mag is loaded correctly. Zig Zag back and forth keeps the bullets even and on the right plane for insertion into the chamber. If you have one off just a bit them bam it's trying to go in sideways.

All six of my magazines are "old style" and I've had zero malfunctions in over 3000 rounds.
