Isn't it suppose to take all AR style mags. Steel and aluminum magazines will not seat in the mag well, is there something that I am missing?

If I do get them to seat, I can not remove them from the mag well.

Who do I contact about this, as it is a brand new rifle?


Posted in the industry forum as well.


I spoke with Paul at MSAR and I am sending the stock over to them in the morning. They were very professional, and he called me right back (With in 15 min. of my call). I am very satisfied. Great C/S.

Thanks for the info guys.

There are several threads on "stuck mags" in this forum. It's a very well known issue.

E4 Owners! Got mag issues? Were you aware of the recall? Upgrade = Good!

Go to the MSAR website and follow the directions for the magazine catch upgrade.

From MSAR's website on thier bulletin board.

MSAR’s XM-17 E4 Upgrade
August 4, 2010

MSAR’s XM-17 E4 variation of STG that accepts M-16 magazines.

This is from the MSAR interal forum-

We are offering a free stock magazine catch upgrade. All current E4 stocks were manufactured w a composite internal magazine catch. We are finding that this composite is failing in their assemblies causing magazines to become stuck or locked in the stock housing. The new catches are made of heat-treated stainless steel.

Please contact our customer service manager Paul Thomas for this upgrade.

300 Chestnut Street Bradford, PA 16701
Phone: 814-363-9260 ext 14

We apologize for any inconvenience this has caused. We greatly appreciate your interests in our products.

Anthony Marfione – CEO MSAR inc.

I sent my stock off on Thursday 8/19, it arrived at MSAR on Monday 8/23, and I had a UPS "attempted delivery" notice on my front door on Wednesday 8/25!

Am I the only person on earth who hasn't had an issue with my E4?

Mine's been fine too. That said, I am sending the stock for the free upgrade.

Nope Joe-I too have never had this issue with my E4 as well. I can insert any mag I have for the E4 (includes the msar mags, some pmags, and a stoner mag) and get it out with no issues. I am still debating on sending it in for the upgrade. I may go out to the range later this week, and after that I may just then decide to contact Paul about sending it in...

I never had any problems either, except for when I tried one of those crappy SIG mags. Then it got stuck. But other than that i love my E4.

MSAR is aware of the problem with stuck mags and they will repair at no charge.

of course, you could go with the STG and avoid this problem all together...

I'm at a 'simplifying logistics' point in my collection, or hoarding, or stockpiling or whatever the hell it is I'm doing. The mag compatibility was what pushed me over the tipping point in getting a MSAR.

What is the general turn around time? I sent mine off well over a week and mum is the word.

If I do not have it back by Friday, I will call them.

I know that I am being overly impatient, but I really, really want my rifle back.

If it's been over a week, it sounds like it is time to call to see where it's at...

I am willing to give it a couple of more days seeing that it was a holiday weekend. If I have nothing by Friday, I will call.

Oh yeah-I keep forgetting about that seeing as how I had to work the holiday, so to me it didn't exist!

It arrived today!!!!!
