Hi. I have a preban 30 round mag that i have for when i go to nevada to shoot and it sometimes double feeds and causes jams. Does anybody know if just replacing the inside with new parts will fix it. I dont think it's the frame with the fault, i believe its just the inside feeding it wrong.

Do I need a different mag or just new internals?

I dont have much knowledge on this so any insight will be great. Thanks

you realize if your rifle is featureless you can shoot your 30 rd mags in CA right? you can fix any part in the mag with a new part..

If you have had it for 10+ years and have been using it, it's probably the feed lips. Mags kits are cheap.

Mag lips would be my guess too. Just buy a mag kit and replace:

Agreed. Do you store your mags loaded?

Could be anything... if it's old, it could be one of the **** rushed mags before the 94 ban.

I suggest replacing the spring (in case it has gone weak), the follower (with a Magpul anti-tilt one), and the body (in case the feed lips are to blame).

That way, all your bases are covered.

Not if it's the base plate!!! :clap:

A magazine rebuild kit is probably the best best.
SIDE NOTE: Is there any side effect to storing mags loaded? I'd heard about storing pistol mags loaded to relieve a little tension on the springs so they load easier, does the same hold true with AR mags?

Pmags shouldnt be a problem storing loaded since when the dust cover is on, it takes the pressure off the feed lips.

Over time, the constant pressure can results in feed lips being spread. This is why PMAGs come with a dust cover

I've been running a couple tests on PMAGs to see what effect leaving them loaded without the dust cover has. I shot the one-year mag a few weeks ago without any issues...we'll see what the two and three-year mags do :D
