CA M16/M4 68Rd Mag Question
 

I have an Classic Army M16/M4 68rd Mag. It only seems to fit 40. I can see a bb in it that won't come out. I have tried pushing the little tab that holds them in the mag, but the spring won't push it out. Anyone have any ideas?

Could you possibly have gotten one of those oddly shaped bbs stuck in it? I know a couple of our guys have had this happen with high caps and an messed up bb jammed the mags all up.

Did they fix it?

I took apart the mag, and once I had the last screw undone the spring popped open with the remaining bbs. I tried putting it back together and in the process I lost the small spring that holds the tab that keeps the bbs in.

After a lot of swearing, I broke apart a pen and used it as a replacement. Who knew it would fit perfectly.

There was a small circular piece or rubber that was at the enterance of the bb opening. I think that piece was causing the jam in the first place to tell you the truth. I remember it being twisted around the problem bb in the first place. I didn't know what the purpose of the piece was then, and I don't know what it does now... I hope I won't miss it.

Thanks for your help! It seems to be working for the moment.

Here is an image that a guy at Arnies gave to me. It's in Japanese, but you get the idea of how the mag works after looking at the pic.

Sounds like an o-ring. I've seen it with KA mags and it jammed up one of my mags. I forked the sucker out of there and we've been happy ever since.

Is it an o-ring from the M16 mag? I heard it might be from the TM Speedloader. Either way, it seems that both are working fine, but I feel weird having a part sitting in a bag when I know it fits in somewhere.

Kinda like after I put together my self from IKEA.

Wow assembled yourself? You are gifted!

Gotta love typos eh? I knew it was shelf but couldn't help point it out...

No no, I am a T-800 Model 101. :)
Look for the T1000 in the spring.

I've had the same o-ring stuck around a BB jamming it, no idea where it came from, was in an M4/16 MAG midcap.

Try taking apart the mag. Careful not to loose any of the parts like i did :banghead:

But you will be able to get rid of the o-ring. It takes a bit of fiddling to get the whole thing back together because the springs keep wanting to bust out. PM if you are having trouble.
