C.C.U. Upper for Glock is available for the following Glock models:
G17; G17C; G34; G19; G19C; G20; G20C; G40; G21; G21C; G41; G22; G35; G22C; G23; G23C; G31; G32; G32C and the respective 'SF' models - (All Gens)
NOTE: Factory Loaded Ammunition Only. Mech Tech recommends only using good quality factory loaded ammunition in the CCU which meets SAAMI, CIP or NATO standards. The CCU is a blowback operated action and is capable of safely firing ammunition up to +P. DO NOT USE +P+ or 'hotter' loads.
NOTES FOR CCU's WHICH FIT GLOCKS
The CCU's fit Glock frames that are Compact (G19, G23, G32), Standard (G17, G22, G31, G34, G35) and Large (G20, G40, G21, G41). Mech Tech Uppers are not available for sub-compact Glocks. An interesting fact relates to Glock magazines. A frame separated from the slide and barrel will physically accept a magazine of a cartridge different from that for which the assembled pistol is designed (using magazines designed for the same series of frame sizes). What this means is that a Glock pistol & CCU combination can be set up to safely fire a cartridge different from that for which the assembled pistol is designed. Example: The frame (lower unit) of a Glock designed to fire the 45 ACP cartridge in the assembled pistol can be safely used with a CCU Upper designed to fire the 10mm cartridge. This is accomplished by assembly of the 45 ACP Glock frame to the 10mm CCU and the use of a Glock 10mm magazine designed to be used with that series of frame size. 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 Mech Tech Systems Inc.
NOTE: 357 Sig - this is a bottle necked cartridge. The CCU is a blowback action and therefore will work the brass during firing causing the shoulder to be set considerably forward. Re-loading the brass works the brass even more and may result in case separation when firing. Mech Tech has a 'factory ammo only' policy for all cartridges.
Note: the CCU is not associated with Glock or endorsed by Glock - it is designed and manufactured in the USA.
The "Feed Ramp"
The Feed Ramp is placed in the Glock lower. This item is necessary for proper feeding. There are 2 sizes - specify Glock model when ordering. One Feed Ramp comes with each CCU. The block is not actually
attached to the lower - just sits there during assembly of the CCU upper.
When the upper is in place the ramp is trapped. A small magnet keeps the ramp in place during assembly/disassembly.
This is the starting point to design your customized CCU. It comes with a 6" picatinny rail. The only required add-on is one of the stocks/adapter pictured on this page. We install your stock and any rail upgrades you select from our ACCESSORIES page, free of charge. Every unit is test fired before it ships. It also comes with one feed ramp.

M4 Stock Adapter
This adapter attaches to the rear of the CCU housing. Many customers already own an M4 stock and buffer tube. The adapter accepts both military and commercial buffer tubes.
This is a 4 position telescoping stock shown fully extended and fully collapsed. It has a sling stud for attaching your own loop.
This photo shows a standard M4 stock (shown fully collapsed) with buffer tube mounted to the CCU using the adapter shown in the photo to the left. The M4 Adapter comes with this stock and so is incuded in the price shown.
NOTE: "Glock" is a registered trade name and Mech Tech Systems Inc. is not affiliated with Glock. Glock has not endorsed the CCU and the fact that Mech Tech Systems Inc. provides the CCU as a Glock accessory in no way is intended to imply that Glock sanctions or is in any way associated with the product.
