Fat P-Mags

[lebl468]

I picked up a Magpul P-mag for my Olympic lower, but the only way I may get it into the mag well would be with a rubber mallet. Anyone else had this problem?

 

[Paulinski]

Could be your lower - Olympic is not known for greatest quality.

 

[jdman]

Try it in another AR. Most likely its the lower.

 

[lebl468]

Even if steel mags fit good?

yes

 

[sparrow]

It's your lower dude ...

 

[Jamie]

I will trade you a steel mag for your P-mag and pay shipping both ways! lol

I was thinking about offering the same thing.

 

[Jamie]

great minds think alike!

 

[lebl468]

Ha! Thanks for the offer, but I already have steel mags! I just liked the quality of the P Mag.

 

[ESQ]

Pmags are injection molded. There isn't any variance in the mags. Has to be the lower.

 

[weaverd]

is it possible you have one of the 308 pmags

 

[lebl468]

Nope, it has 5.56x45 printed on the side. I just got done some fine Dremmel and sand paper work and it fits good now. It was tight on the backrib, and back corners. Fits snugger than the metal mags but can be pushed in with 2 fingers.

Is it the newer M revision or the older model?

 

[lebl468]

Pmag 30M

 

[hbean]

all it takes is one manufacturer to be a thousandth skinnier on the tolerance and the other to be a thousandth fatter to cause problems.

I wish our PMags were fat... Fat full of ammo

Some of the early P-Mags were a little fatter than many in-spec ARs liked and the fit was tight and/or mag did not drop free. This issue is one major reason why Magpul did the P-Mag revision, changing specs for the mould and a few other tweaks. I have both older P-Mags from the first production runs and the latest. The older mags were "fatter." A little light sanding should fix the problem.

I have a bunch of Pmags dated 07/07 that work well with all lowers I have tried them in.

I also have a bunch of Rev M dated 03/09 that are alot tighter in the magwells. Maybe the tolerances were changed in later models?

 

[lebl468]

I removed a little material from the back and corners of the mag and it works great now. Doesn't hold the bolt open on an empty mag.......but oh well.
