G&P Ready Mag System
This was my first attempt to add a larger battery to my M4 R.I.S. It's an all metal build and utilizes the stock mag release to release the mag in the ready mag. It also comes with 2 rubber sleeves to protect the M4 body when attached.

To make it work as a external battery holder, I needed to first drill a hole in the inside, top of the ready mag system. I then created a mini battery extension cable with 1 connector inside the ready mag and 1 outside ready to connect to the stock battery connector. I simply removed the inner workings of a stock M4 Magazine to hold a larger capacity battery. To keep the battery/mag from releasing when an actual mag is released, I put i layer of duct tape on the outside of the battery/may to hold it in place with friction. This worked well and kept the functions of the ready mag in tact.
The down side of the ready mag system for me is when I added a Sun Project M203. There was not enough clearence from the front of the magwell to accomodate the proper alignment of the entire M203.
