MAG Mags Not Feeding in Combat Machine

[Jokerthepilot]

I bought a pack of MAG midcaps to go with my Combat Machine, and they aren't feeding properly. They sit too low in the magwell, about a millimeter, and if I push up on them while firing, they feed flawlessly,but it's very inconvenient to have them stop feeding as soon as I let off pressure on the mags. I tried shimming them with tape, but it peels off after only a few mag changes. Any ideas?

Like I said yesterday and today, put a piece of sticky velcro (soft side) in the magwell whereever it seems like it will be most useful. It will shim that mag into place, but will also compress if you use a different mag.
