recently bought some 20 rnd. gen3 pmags to try out.
this is my first experience with polymer mags and am glad to say they work just fine. one thing, how do the feed lips hold up to long term storage with the full load of 20 rnds compared to steel / aluminum mags? are they prone to spreading? does using the dust cover help? thanks. |

I have only seen one complaint about feed lip spreading on the M3 versions. But in the post the OP turned down Magpuls request to look at them for some reason. The whole thing was suspect. Other wise they are good mags and have been in use for a long time. Plus Magpul stands behind their product.
And like Dennis2313 says you can put on the dust cover to take the pressure off. |

Quoted:
The dust cover depresses the rounds down a little so there is no pressure on the feed lips while the cover is in place. Magpul has said that the dust covers only purpose is to keep crud out Edit: Either way though, I've never heard of a problem with Pmag feedlips spreading. And magazines are supposed to be disposable anyhow. |

Loaded them up, you won't harm them in any way. They are built with extra head-space to make sure dust covers can be applied and/or for the user to be able to insert a mag on a closed bolt. On most Pmags you can actually load an extra round, although I don't condone it. Those feed lips will be just fine. |
