Airsoft Hi cap to Lo cap conversion plug

Planning on some airsoft games that are closer to realistic. In need of magazines that are closer to low cap or milsim capacity. Didn't want to permanently destroy or alter the mags because they are expensive and I'll use them unaltered in the future.

To print and make it easy to install and take out slice it in half and print on the solid flat side. Lettering added to label which magazine it goes to. They are all similar but just different enough on the internals that they are not all interchangeable.

These currently just limit the amount of rounds that can be fired from the mag, due to it being a self loading design from a reservoir. The wind up design of these mags leave about 20-30 in the tube without enough tension to feed, so effective capacity is 70. 

The main feature of these plugs allows the mags to be loaded quickly with a set amount of bbs without leaving the cavity so empty it makes a crazy amount of noise.

I have other brands and models of high cap mags from my friends and family that I will be making these for over the next month or so when I have time. 

Bookmark this to keep tabs or comment the brand and capacity you have and I'll see if I have it in the queue and if I do I'll prioritize getting it out.
