So I just received a cool Gen 3 Magpul 20 rounder from a friend today, and I don't know about you guys, but I do really like the feature that allows the dust cover to snap on the bottom of the Gen. 2-30 round magazines.

Unfortunately the Gen 3's don't seem to share that feature.

Don't know about you guys, but sometimes while working on a car, I've spent more time looking for some tool that I had just set down somewhere, than I have actually spent working on the car itself...know what I mean.

Anyway, I modified this Gen 3 mag. so that I could snap that cover on the bottom and it works pretty darn good!

...but I'm not quite ready to show you the experimental hack job that I did to the back of that poor magazine in order to get it to work.

I prefer the gen2s for this reason, hopefully they will bring the concept back on the gen4s

I hate how the gen 3 pmag 20 rounders are curved. Just one more reason not to buy them. I always liked the straight gen 2 20 rounders, but I cant find them anymore

All my G2 and G3 mags have Ranger plates so if one could figure out how to retain the dust covers in that configuration, that would be spectacular.

I've never done much dusting whilst wearing / carrying mags so I don't see the issue here. Besides, how are you gonna slam that mag home with the extra plastic dangling there?

I picked up two 10 round mags yesterday for the 300BLK I'm planning on building.  That was one of the first things I noticed.

I just figured I was doing it wrong

I think I have a box of dust covers around here somewhere.  I don't see a need for them.

I was lucky enough to find 2 black Gen 2 20-rounders in a local pawn shop last week for $6.99, each. I couldn't pay for them fast enough, lest they realize the market price is almost triple that.

They make no sense.

While in storeage they are protected from dust by what ever container they are in.

While being used they are taken off.

In both situations they Arn't needed.

Agreed. When I buy new PMags, the covers get popped off just once....directly into the junk drawer, never to be seen again.

I thought their main function was to take tension off the feed lips, rather than to shield from dust.

keeps pressure off the lips... i find them important for long term storage with rounds in the mag.

Same here, or thrown away.  Never really saw the need.  I have mags from I think 07 that I run routinely still and they are loaded all the time.

Well since you asked, you are exactly nobody of any consequence, when it comes to what the manufacturer has said over and over and over and over and over and over.  That they are not needed, and they do nothing to, or for the feedlips.  

You know, storing mags loaded over a week, will ruin your spring too right?

How!?!  How do you ever manage?   This cannot be possible!  You must have no idea of what messed up feedlips look like, or you'd surely know you have them!

I like the covers. But they only do just that until they are needed. If I loose some, ill buy some more. They are certainly cheaper than most things about my rifle. ;)

But that was the selling point when they were introduced, the koolaid has affected your memory.

13ers gonna 13




Magpul DID put that in their patent description.




So, while I too am nobody of any consequence, I do know how to read.







Scroll down to Detailed Desciption,next to last page, half way into Section 5

















"protective cover 40 also provides reinforcement during storage, as pressure from the stored ammunition and spring 35 would normally force the feed lips 21 of the magazine 1 apart. Protective cover 40, shown in figs 10 – 10c interface with geometry, namely notch 44 and hinge base 48, on the magazine body 10 with latch 43 and cover hinge 47 forces the ammunition downward within underside spacer 45 thereby absorbing and distributing the forces that would normally be applied to feed lips 21 in a more advantageous manner.

13'ers...great comback.  I was here a long time before I registered, but then again, I really have exactly nothing to prove to you or anybody else.  I can only attest to what the guys who make the product, have said over and over and over.  Yes I get they said it may help in the beginning, but I think they have been proven unneeded.  

I drink no koolaide.  I have several hundred mags, of Magpul, Lancer, and USGI flavors.  I buy good shit, and I get exactly what you get out of good shit.....not many problems.  You want to obsess over covers?  Be my guest.
