I was inspecting these new space-age fancy Pmags when I noticed how well they line up to the feed ramps. So well that they cover up M4 feedramps. In other words, the tip of a bullet being fed would never even contact an M4 feedramp. :eek:
The more I study these mags, the more I’m convinced that they’re a completely superior design.
Here’s some half assed pics of my Pmag vs. a Standard mag research. Note that on the exact same upper, you can’t even see the M4 feedramp when the Pmag is seated.
Interesting point, but it looks to me like even the aluminum GI mag covers up the ramps. I’m trying to picture how a round would clear the mag and then nose down at such a abrupt angle to catch on the receiver.
You’ll have to check it out on your own weapons since the pics aren’t that great. But the USGI mag does meet the very bottom of the feed ramps on this COLT.
Even so, I believe the PMags are a superior design. I have quite a few now, and prefer them over the aluminum USGI mags. No more fucking up your mags when you step on a dropped mag by accident.
I don’t track on your post. The entire point of my thread is that PMAGs are insanely superior in design. A mag that won’t give a bullet the opportunity to nose dive under any rate of fire is brilliant.
The PMAG means you don’t NEED M4 feedramps.
Pmag are what the mag should have always been if it weren’t for the constraints of stamping metal.
Repsectfully demigod, a pic of rounds in the Pmag would of really driven your point home. I’d love to see a comparison pic with the rounds presented higher with the pmag. I have two pmags and I too am a believer. I ran them both thru my Stag upper/Mega (non M4 ramped) lower fully loaded to 30 rounds with NO problem. I LOVE how they unload by hand easily. Harold H.
Anyone can check this out for themselves at home. But actually, the better comparison would be emptying the standard mag to get the ammo out of the way to even better show the difference… I just didn’t feel like unloading and reloading that mag.
A round physically can’t feed any lower than the front of the mag body, and the front of the pmag is higher than a standard mag.
Did anyone stop to think why M4 feedramps were developed in the first place?
It’s because during FA fire that the bullets can and will be stripped and pushed forward much lower than usual.
Supposedly there’s a dynamic that exists between the rounds and the mag spring and the rounds can actually not be up where they need to be- either because the spring isn’t pushing them “fast” enough or they get bounced back down during recoil- I forget which.
But, the ramps are down lower for a reason. If the Pmags won’t allow a round to be stripped low enough for the tip to hit the ramp then there is something wrong with the Pmag itself.
I understand Mark that your only point was that it negates the ramps. The tone of the thread has gone towards this being a good thing.
I don’t think the M4 ramps were every really all that necessary in the first place so this isn’t that big of a deal.
