The Generation M3 PMag from Magpul is the latest and greatest version of the original PMag. With a revised body design that allows this Pmag to work in virtually all foreign and domestic modern sporting rifles, these may be the last PMags you ever need to buy. Performance, reliability, and durability have become the hallmark of Magpul's flagship product and now with the enhancements brought by the Generation M3 you may be looking at the finest AR15 magazine ever designed.

Some of the enhancements with the Generation M3 PMag are easy to see when comparing to the Generation M2. The biggest difference is the Generation M3 ships with an impact dust cover that will keep debris out of your magazines when it is installed. You may also notice the floor plate of the Generation M3 is slimmer allowing them to fit better in tight magazine pouches. There is also an over-insertion stop built into the spine of the magazine body allowing you to perform aggressive magazine changes without risk of damage to your magazine. There is also a marking dot matrix on the bottom of each magazine body which will allow you to quickly identify your fully loaded PMag with the exact ammunition for the task at hand.

Makes PMAGs even better
Review by Keepshooting Customer
It has all the great things of the Magpul magazine plus a peep hole. Can’t get much better.
They also have covers to cover the hole so if needed it can be sealed off. Great all around and good looking.
