This item is perfect, I'm running 4 extended glock mags, and was initially worried they might ride too high and loose, but I placed the insert high and the mags fit dip into the rig and are very sturdy.
WARNING: This insert is ONLY compatible with the Micro Fight MK3 Chassis. It is not compatible with the MK2 or MK1 Chassis, nor plate carrier kangaroo pouches.
Some people say that Sub Guns are a thing of the past. We say to hell with that. It doesn't matter if you are storming the Iranian Embassy in 1980 or raiding a meth lab in the Bayou today, the Spiritus Systems Submachine gun inserts have you covered.
Submachine Gun Magazine Inserts enable you to carry 4 magazines in either the front or rear pocket of your Micro Fight Chest Rig, or you can carry 8 magazines by placing an insert into both pockets.
To accommodate the largest amount of magazines, we have built two different types of SMG Magazine Inserts. It is impossible for us to test every submachine gun magazine that is on the market today. That being said, the inserts are elastic and if your magazine is similar in size to the ones listed, it will probably work.
NOTE: MP7 Magazines fit in the MPX/Scorpion insert.
