They will not latch in, anyone have a solution to this problem.

I had the same problem after buying 20 Pmags!  Spoke with a friend at my local gun club and he solved the problem with a dremel!  Takes about 15 seconds and only requires filing down the small ridge on the Pmag that won't allow it to insert.  Let me know if you need pictures and I'll put some up.  All of mine fit perfectly now and are as tight as can be...they drop instantly and are fantastic!!!!  Hope that helps.  

This is a known issue with some S&W lowers being a bit out of spec. A little material needs to be removed from the PMag as mentioned, and it should work fine.

A picture would be nice, thanls jim.

The area that needs to be worked on is the front of the mag, right at the op of the ridge.

Hope this helps.  It's only the top part of the very first ridge that needs to be slightly filed.  It's a piece of cake and works great. http://i219.photobucket.com/albums/cc40/hookalakupua/DSC01252.jpg

By the way.  if you contact S&W after the Holiday Break, I believe they'll either replace your lower or take it to spec.  I'm sending mine in.

We got a M&P15T in last month and it works with PMags just fine so new guns seem to have been fixed.

*Stops kicking the sand...I hope you see this reply. I am new to this site, and it is great to hear from people in the industry. This is an industry where one must do one's homework to determine who makes the best product/parts of the dozens and dozens of manufacturers out there, once that is done it is inevitable that there will still be a few choices remaining. That is when it is time to pick the American made product with the best customer support out there. Thanks for putting my mind at ease, I was just about half a hair away from placing my PMAG order when I read this. Now I wish I would have went through with it so I would have had them when my rifle came in.P.S. I love me some MASADA (wonderful name even). I will have one before 2008 is out (unless I win the lotto before new years). It is downright treason that it was not chosen for the extreme dust testing with the XM8, SCAR, 416, and M4. Did you guys shoe polish some R&D guys car or something? They are mad. To offer the reliability with the gas piston system WITH caliber interchangeability (is there suh a word?). It was my states rep. (Coburn) who brought up the issue, but he has no industry knowledge. It seems he was just responding to troop complaints and it got messed up from there. he needs to know about this rifle and ask why it was not selected for testing, we can afford the best for our troops so why give them anything else? I am writing him about the MASADA...

I have 8 pmags and two S&W AR15's and they all work with no problems....

I filed them down and they fit now.

Every other mag I have fits great sooo are the S&W lowers a bit out of spec or the PMAGS?  Maybe it would be better to mod mags to have them fit extra tight as oppossed to "fixing" the lower and risking having some other mags be too loose...

Exactly.

I just finished a 3 month eval of three M&P15's, in which we fired 23460 rds.

The PMAG's fit in two with no problem. The third, a "newer" gun (ser# 55xxx) would not accept them.
In this case, the mag well was not beveled. That is, it did not meet specs.

If you go to 10-8 look for the thread Magpul Lowers. I have a pic of that same gun next to a Magpul lower. Ray Charles could see what the problem is, and it is the magwell being out of spec.

Contact S&W if you have this problem.

So, do you file the front or back of the magazine?

Edit: I tried to file one of the 8 and I got it to fit.  It won't drop free now.  Oh well, I am selling the other 7 in the EE now.

I flied the front and just like yours it won't release now.

Me too.

 As do I.

It is now.

Please do!

My Pmags lock in place but the bolt will not move forward.  Anyone have this issue?  Seems to be a bit of a different concern than teh others.

Talked to S&W yesterday, they said send it back and they will modify the mag well.

Dear Mr. Solidius,



Thank you for your message regarding the Magpul Masada rifle. I appreciate your recommendations.



My staff and I are familiar with the successes of Magpul. They are a great example of how American creativity and innovation can build better products. However, my intent in pushing for the Army to compete its new rifle procurement is not to steer them toward any one particular product - only the best one. Through a full, fair and open competition, I am confident the best weapon system will be found. Our troops deserve nothing less. I am confident Magpul's products will be a formidable challenger but it is nonetheless my desire to let the competition play out and allow the Army to review the findings.



Thank you again for your message and for your suggestions. I value your opinion and I hope you'll keep in touch.



Sincerely, A

Tom A. Coburn, M.D.

United States Senator

Check the top of this page.

hmmm, my pmag wasn't locking in at all untill i altered it as seen in that picture. after altering it with a dremel it now locks in just fine, but it still wont drop free. it feels like there may still be friction on the sides of the magazine.
