Damn, now I feel cheated out of $5 that could have gone toward the $18 S&H fee.

do you have an approximate count of how much this increased your capacity?

Removing the plug increases it to 120 count versus 100 count.

Nice to know.

Just did this to the newly received box of M4 mags....it works great! The last few BB's don't feed due to the loss of spring tension, but you still get at least a 10 BB increase per mag.
Took me all of 5 minutes for all 8 mags.
Works for MAG G36 magazines as well.

I wanted to post an update to my experience with these magazines.
After using these magazines for a couple months (probably 6 skirmishes), I've noticed that the magazines have begun to have problems feeding properly. This happens both in semi and fully auto. I thought perhaps the spring was compressed, so I removed the spring from each magazine and stretched it a bit, making sure it wasn't kinked.
The problem continued over the next two times I skirmished. After last weekends skirmish, I was removing the left over bb's and noticed that in several magazines the bb's were wedged inside the track, about 1/8th to 1/4 inch below the opening. Smacking the mag once or twice would dislodge the jam.
I should mention that I do a pretty decent job on maintenance. I remove the bb's from them after every skirmish, keep them pretty clean, and store them in a dry area. I haven't actually used anything to clean inside the mag, but that will be the next step in troubleshooting this issue. I'm also going to spray a little silicone lube in there.
I'll post an update as I try to resolve this issue.

I experienced the same symptoms with my MAG M4 magazines after removing the plugs. I then reinstalled the plugs (actually they were shak's since I threw mine away!) and the magazines performed well all weekend during Op:Bulldog.

Thatís interesting Village.
I purchased the 120rd magazines, so I never had the plugs in the first place. The other thing that is interesting is that the jamming is occurring within the first 20-50 bb's on my magazines. You can actually see two bb's wedged in the track, almost beside each other. Thatís where I was thinking the silicone spray may help alleviate that problem. Let the bb's slide up the track a little smoother. Can't hurt it.....
