    Hey Guys,
    Kind of nubie question here. Other then actually burning up ammo what is the best way to determine if the lips on AR mags are out of tolerance? I have something like 8 30 round Colt stamped AR magazines that I inherited that have been kept loaded for about 4 years and I'm concerned about the lips being out of tolerance. I did a quick search and could not find any links to specs or anything else that looked helpful. I appreciate any advise you guys could give, thanks.

    not an expert but you could load the mag in the rifle and manually cycle through them... not the best of course. i think you have to field test to be sure.

    The magazines won't be out of spec in any way from being loaded for 4 years. In fact they're in the same exact condition they were in when they were loaded 4 years ago and set aide. Magazines sitting for years don't have any issues, they do when they are heavily used.

    Thanks, that is great news. I did not really want to buy a bunch of new mags, I would rather spend my money on ammo. :)

    Be careful with this and a free floating firing pin. If you doing this in your living room you don't want to be the 1 in a million to get a slam fire. Can make wife grumpy. I would do this at a range or use dummy rounds / snap caps.

    Probably only an issue if it has soft primers.

    Very fine safety point! A friend had a 223 fired into his attack a few years
    ago. The neighbor behind him was showing a friend his new AR and shot through
    his wall across the back yards and into the attick of Bob's house. :faint:

    Shoot with all your mags, and number them as well. That way you know if you have a problem with a particular mag, and can identify and eleminate it before you really need it.
