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: Mech-Tech 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 Glock pistols have three basic frame sizes - 'Full Size', 'Compact', and 'Sub Compact'. Mech-Tech Uppers are not available for sub compact Glocks. In the 'Full Size' series are the Models G20 (10mm), G21 (45ACP), G17 (9mm), G22 (40 SW), G31 (357 Sig), G34 (9mm Long Slide) and G35 (40 SW Long Slide). Within the full size series there are two frame widths as is the case for the compact series. 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 Feedramp is placed in the Glock lower. This item is necessary for proper feeding. There are 2 sizes - specify Glock model when ordering. One Glock Block comes with each Basic unit. 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 block is trapped. A small magnet keeps the Block in place during assembly/disassembly.
This is the fundamental unit you order to fit your Glock. It comes fully assembled and test fired. It includes only what is shown above plus one standard Glock Block. Nothing else is included with the BASIC unit. At the right is shown what can be done by adding accessories. Accessories are ordered separately - see ACCESSORIES page.. Please specify Glock pistol model when ordering. Accessories which are ordered at the same time you order a BASIC unit include free installation.
