This is a body kit for Tactical Force's airsoft CO2 Mac 11. The features of this were inspired by Rainbow Six Siege's SMG-11. It includes:

A rail adapter for a foregrip, flashlight, laser, compact grenade launcher, or other accessories

A 14mm threaded muzzle for attaching a flash hider, silencer, tracer unit, or other accessory

A rail for mounting an optic of your choice

A side-folding stock adapter for those who do not like the folding wire stock

The side-folding stock adapter uses the stock and latching mechanism from a cheap MP9 AEP. The stock is sturdy and does not wobble at the mounting point. The AEP in question can be bought here for about $30: https://www.evike.com/products/38496/

To attach mine, I used plastic epoxy. As such, it will be very difficult for me to open up my gun for maintenance. However, the only issue I have had in this gun was the lever for the safety falling out. It is a sturdy airsoft gun, and as far as price goes it is pretty cheap. I got mine in a boneyard lot, so I did not spend nearly as much as I would have if I bought it new. If you are careful you should be able to attach the front rail and 14mm adapter without having to worry about locking up the disassembly. Additionally, you should be able to slide the stock adapter into the gun without glue. However, if you do not use glue with the stock it will not be nearly as sturdy as it would be otherwise. The only part here that does not play well with disassembly is the optic mount. With a bit of modification, you should be able to make a longer body pin that will go through the sides of the optic mount, thus eliminating the need for strong glue.

Due to the policies of CGTrader, I am unable to show the body kit installed. It does work, and it works well.
