Some people say that Submachine 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 a Submachine Gun insert into both the front and rear pockets of your Micro Fight Chest Rig Chassis. 

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.

Spiritus SMG insert
Written by Andrew Tokarczyk on May 23rd 2019

I purchased this with the intent to use it in a Haley Strategic D3CRM as the Haley inserts never seem to be in stock. I can report that it fits perfectly! I use the larger option for scorpion mags. While intially it can be a pain to get the mags inserted, after some breaking in they slide right in. Re-indexing mags is easier than I thought it would be considering there is nothing holding the top open. Overall very please, seems like quality construction, time will tell. Happy with my purchase

Fits KP-9/KR-9 mags exceptionally well!!! Also, if you’re thinking about installing this is in a Haley Strategic chest rig, it fits quite nicely.

Perfect Fit, Form and Function

I ordered the MP5/Glock magazine option for 33-round 9mm Glock magazines. The item arrived quickly. The magazines fit perfectly and had no unwanted movement. I installed the insert in my MK. 3 chest rig using cardboard pieces. The centered insert had a little room on each end inside the chest rig slot. (I could probably jam a chemlight in the space) I jumped up and down, did a handstand, twerked and danced the hustle. The magazines stayed put. I fully recommend this insert if you're running a pistol caliber carbine.

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.
