C.C.U. Upper for Glock is available for the following Glock models:

G17; G17C; G34; G19; G19C; G20; G20C; G21; G21C; G22; G35; G22C; G23; G23C; G31; G32; G32C and the respective 'SF' models - (All Gens)

(Note: MechTech advises the use of factory loaded ammo only for all CCU's) The CCU is a blowback action and therefore is ammo sensitive. If you are experiencing ammo problems try switching brands. For instance reports have been received relative to Underwood as being a problem brand.

NOTES FOR CCU's WHICH FIT GLOCKS

The CCU's fit Glock frames that are Compact, Standard and Large. MechTech Uppers are not available for sub-compact Glocks. In the Large series are the G20 (10mm) and G21 (45ACP). The Standard series are G17 (9mm), G22 (40 SW), G31 (357 Sig), G34 (9mm Long Slide) and G35 (40 SW Long Slide). 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 MechTech 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.

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. MechTech 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"

Insert the 'Glock Block' into the Glock lower. 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.

Yes, it looks like an M4 adjustable stock. However, we have replaced the buffer tube with our own adaptor. It has only one position, on or off, so it is in effect a fixed stock. FSD $34.95
