MechTech Systems presents a novel Upper - the

Carbine Conversion Unit

A revolutionary accessory that will change the way you see your pistol!


What exactly is the CCU system? It is an 'upper' for an autoloading pistol. Shown below is a photo of what we call Model 1. This is the entry level for both Glock and 1911 pistols, see those pages on our site for additional models. Our Springfield XD model should be out by the end of 2014. You can add any number of accessory items to the models, such as sights, adjustable stocks and additional rail systems. The CCU is not a firearm and requires no special licensing to purchase. Under federal law (BATFE) it is perfecty legal to install a pistol lower and then remove the lower and reassemble the pistol. (see forum and FAQ pages for details) The unit comes completely assembled and test fired. Installation of stocks, rails and flash hider, see our Accessories page, ordered with the initial purchase is free.


Model 1

Shown above is a Model 1 CCU for Glock. All models have a 16" barrel and fixed stock. Yes, . The basic unit is NOT a firearm and needs no special licensing to purchase! What do you need? You need a Glock or 1911 pistol. What do you need to do? Field strip your pistol. This will separate the 'top end' assembly from the frame or 'lower'. Shown below is a Glock with the 'top end' removed.


Glock pistol 'lower'

Now you slide the pistol lower into the CCU and you get what you see below:


Assembled unit - ready to fire!

At this point you have your pistol with a 16+" barrel 'top end'. The unit is ready to fire! Slip in a loaded magazine, rack the cocking handle to the rear and release it - this loads a round into the chamber in the same way as does the original pistol slide. The unit operates in semi-auto mode exactly as does the pistol with the original 'top end' in place. No modifications to the pistol 'lower' are necessary. No unusual wear occurs when using the CCU. The assembly is totally reversible. MechTech has a whole family of accessories to customize it for your needs. Accessories which attach to the rails - eg: sights, lights etc. - are a 'no brainer' to install and this will be left to the customer. Please see our ACCESSORIES page to see what we have available plus you can use some of what you may already own.
