Yes—the Z-RAM Tec9-style .68 barrel cover with Picatinny rail uses screws to fasten to the barrel. It is not limited to a matching Tec9 body: Z-RAM also describes using these covers on a regular Umarex TR68 without that body kit.
That answers the fastening and body-kit question, but it does not confirm a fit on every .68 barrel. The specific Toursekev M68 Short arrangement raised in the question, with several protruding barrel extensions, remains unconfirmed.
The cover and the body do different jobs
The cover encloses a projecting barrel section. Its Tec9 styling and smooth printed finish are designed to continue the appearance of the matching body, but that visual match is different from requiring the whole body kit to hold it. This is why a cover can be a separate exterior choice for an existing TR68 setup.
The screw fastening explains how the cover is held. The surrounding body and the barrel being covered still determine the particular arrangement. In the original reply, Z-RAM’s reservation about factory plastics was about how the combination looked—not a statement that those plastics made screw fastening impossible.
Choose the enclosure with or without a rail
Both .68 offers are modular covers for barrels and extensions. Their stackable design allows the enclosure to continue along a longer existing barrel section. Adding cover modules changes the amount of exterior coverage; the cover is not itself a barrel extension.
The rail-equipped version adds a Picatinny accessory interface. The plain version keeps the cover’s Tec9-style enclosure without that added rail. If you only want the covered front profile, compare the plain cover; if you also want the rail interface, compare the rail-equipped offer. These are alternative cover formats, not two parts that must be bought together.
