Ar-15 and Magazine Question
I am new here and have a question about an ar-15...how durable are these rifles and is it ok to keep the aluminum magazines like nhmtg's loaded without the feed lips spreading? Don't the feed lips only spread if the mag is loaded and its dropped or thrown around?
Anybody have experience with this? |

Ha I wouldn't worry to much. One of the members here just had a mag loaded for quite a few years it ran with no issues. do a little searching I'm sure you'll find it

The rifles are very durable and so are the mags. I have some that have been loaded for many years, and no problems.

All what crap? Search around and you'll see that it has been disproved time and time again.

I kept a military surplus aluminum 30 round magazine loaded for something around 22 years.
It was never touched or unloaded, it just sat in the case next to an AR-15 all that time. I took it to the range earlier this year and it fired all 30 rounds with no problems. Before taking it out to shoot I compared the magazine feed lips to a brand new magazine and measured them. The lips had not spread on the old mag in all that time, nor had the floor plate bent or bulged. As for AR-15 rifles, if you buy a good quality rifle it's good for probably longer then you are. Buy lower quality or don't give it good maintenance and you may have problems. |

I wonder if the stories about the AR mags spreading showed up about the same time the 6.8 Rem SPC did? I heard about some of those clips spreading, so I loaded up an old AR .223 mag with 6.8's to see if it would spread... it did when loaded to capacity. But when down loaded by 3 rounds I saw no problems, and I learned that it fed and cycled just as well as my PMI clips.

I only own two ARs, but have have had no issues with either one. My direct impingement rifle is a RRA LAR15 and my gas piston AR is made by Stag Arms. You take care of your AR and if it's a quality rifle to begin with it will last you many thousands of rounds. Early on I got into MAGPUL PMAGs and haven't looked back. I find them to be reliable as all get out, the same as my rifles.

Feed lips won't spread if just kept loaded. However, after thousands of rounds through them, the feedlips can become spread.
The static spring force does not have enough energy to exceed the strength of the feedlips. But give the rounds some velocity hitting the feedlips, and they will start to roll out a tad. With no wood and the aluminum anodized, the AR is one of the most resistant platforms to environmental degradation. Sure, if stored, bores could use a light coated of a rust preventative. Any decent AR can go 10K over 40+ years with nary a worry. Then, depending on the initial parts, you might be looking at springs, maybe a barrel. Bolts should go 40K+. Aluminum gas blocks...just say no. |
