The Carbine conversion kits from MechTech Systems are insanely awesome! 

With more makes and models being added to their repertoire, MechTech Systems is changing the face of the Firearm industry!

Initially made for Glocks, the CCU from MechTech are beginning to add other brands to their trade, 1911’s , Springfield XD’s and more!

The CCU’s fit Glock frames that are Compact (G19, G23, G32), Standard (G17, G22, G24, G31, G34, G35) and Large (G20, G40, G21, G41). Mech Tech Uppers are not available for sub-compact Glocks.

Generation doesn’t matter, but the front rail size does – see the picture and note below. Compensated and SF versions only affect the barrel/slide and grip size respectively, they will work just fine with the CCU. If you have a G31 or G32 you can only order the CCU in 9mm or 40S&W.

Glock magazines are interchangeable within the same frame size, and between the Compact and Standard sizes. This means, for example, that if you have a Glock 22 and want to shoot 9mm with your CCU, you can. Just purchase Glock 17 magazines. Compact magazines are too short to work in Standard frames. Here are the combinations that will work:

Your frame:      CCU Available in:

Compact                9mm, 40S&W

Standard                9mm, 40S&W

Large                      45ACP, 10mm

Again, make sure your magazine caliber matches the barrel caliber of your CCU.

This information is provided only to illustrate the flexibility of the Mech Tech CCU. (Caution: the foregoing does not imply that a Glock pistol designed for a given cartridge can safely shoot a different cartridge by simply switching the magazine – this is dangerous – do not try it! Likewise a CCU Upper can safely fire only the cartridge for which it is designed!) If further clarification is needed please contact MechTech Systems Inc.
