Deep Fire has spent the last ten years perfecting their aftermarket internal parts and upgrade kits and today I will be reviewing one of their latest full tune kits, an M120, standard bore kit for M4 carbines. This kit includes pretty much everything you need to safely run an M120 in your gun, provided your gears and motor will pull back a spring of that power. I will discuss the various aspects of this kit in this review!

I was sent this kit to review directly by Deep Fire, which is based in Hong Kong. In the US, you can find this kit for sale at airsoft retailers such as Airsplat. You can find FTKs for pretty much any gun/spring combination that you might want to run at various retailers, especially overseas ones such as UNCompany and Redwolf Airsoft, so if you want to run a different combination than the one reviewed today, check them out.

Basic Information:
A Full Tune-up Kit "FTK" is designed to give you pretty much everything you need to upgrade your gun in one package. They can be used either as an upgrade, or as a replacement for broken internal parts. Generally, it is less expensive to purchase a FTK than to purchase each of the included parts individually. If you were to purchase all of the included parts separately, you would be paying about $150, so you basically are getting $40 off by buying the whole set.

First impressions/Packaging:
The FTK comes packaged in a plastic box with a foam inner liner that holds everything securely during shipping. The package has a label to indicate what gun model the kit is for, as well as if it is a standard or bore up kit.

Package labeling

Included in the FTK is a titanium tooth piston, ported cylinder, tapered CNC aluminum cylinder head, ported aluminum piston head, o-ring air nozzle, tappet plate, 6mm steel bushings, ball bearing spring guide, and finally, an M120 spring. This is pretty much everything you need to increase the velocity of your M4 AEG.
