I bought a couple of P-mags for my dad's new AR. The 30 rounders would not lock in. They worked fine in both mine and my brothers Bushmasters but not in his M&P. The 20 rounder worked fine. All other magazines have worked fine in the M&P. Any thoughts? |
Good point. There is plenty of room to get 31 rounds in a Pmag. He set "not lock in" I'm not sure if he meant anything like not dropping free or fitting. He needs to clarify this. |
Meaning they were sticking in the mag well? Or they just didn't engage the mag catch? There have been quite a few discussions about M&P mag wells being slightly out of spec. There's not much room for error with a Pmag. If they are sticking in the mag well call S&W and have it fixed. Or don't use Pmags. |
Supposedly just earlier ones but I don't know for sure. That's a great price. I'd buy them anyways. |

My understanding (worth what you pay for it) is that the problem is with the early S&W recievers. Specifically the problem is that the bevel on the magwell was not milled to spec. At one time, S&W was offering to remill the affected recievers. I don't know if they are still doing this. |
They were selling the PMags for $13.00 at the gun show yesterday, I picked up a few and they fit/work fine in my S&W MP15 OR. Mine is in the 804XX SN range. I think S&W fixed the problem they had with the early lowers - go for it.. Happy Monday, Bob S. |
Contact S&W, they will address and fix the out of spec issue. This is a know issue in early S&W lowers. |
Good to hear from someone with first hand experience. Thanks for the input from everyone. |
| I also had a problem with the pmag fitting in my mp15t serial#53xxx, sent to smith and one month later it was shipped back with a new lower installed on it. Shipping paid both ways and even had really good customer service when I had called for updates on the rifle. |
