are there any mag converters for higher cap mags or ones that fit straight on?

I love this spare magazine. Its a whole lot easier to switch mags than to take out one Magazine and reload it. This Magazine doubles the gun's capacity from around 50 to 100. The only drawback is that if you stack the mags you can't fold the stock. Other than that this is one great Product.

This is a mag for the double eagle M85. For those of you who don't already know, the bullets that it displays are just for decoration (so don't worry about your son going on a rampage on an innocent mailman). It holds about 50 rounds, as opposed to the 30 that the description says. It's spring-loaded, and while the gun comes with a tube to fill up with about 30 rounds and push into the mag, I find it easier and faster just to use a speed loader, which also give you the full 50 round capacity. This is the only mag that will work with the M85, so there's not need to browse further if you want to get it an extra mag. It is suggested that you DO buy an extra one, though, because any decent electric gun will burn through 50 rounds FAST. This magazine gets a 3/5 for not being a high-cap chain mag, but still not having any real faults beyond that.

This Magazine is awesome. It holds about 60 bb's. Feels heavy and like it was made of high quality materials. It also attaches to other magazines of the same kind, for quick reloads. I haven't had any feed issues with it. I would definately recomend getting the airsoft speed loader with the magazine.

I bought this spare mags for my G36/M85 rifle and they work as well as or better than the factory one. I like the fact that I can clip two together for a quick change.
