UMAREX Glock 17 Gen5, 19X and 45 GBB Rebuild Kit

Rebuild kit for the UMAREX Glock 17 Gen5, Glock 19X and Glock 45 GBB airsoft pistols: everything that wears through regular use, gathered in a single package for anyone who wants to keep their replica running without hunting down parts one at a time. Not compatible with Generation 4 models, for which a separate kit exists.

The included components cover the parts that wear fastest under gas cycling: air nozzle with return spring, hop-up rubber, hammer with hammer spring and return spring, piston head, and disconnector with its spring. Replacing these parts together, rather than one at a time as failures occur, cuts downtime and keeps the firing cycle consistent over time.

Key points

• Compatible exclusively with UMAREX Glock 17 Gen5, Glock 19X and Glock 45: check the generation before purchasing.
• Includes VFC hop-up rubber, which directly affects BB stability and range.
• Hammer, hammer spring and return spring are included: parts that absorb mechanical stress on every gas firing cycle.
• Nozzle and piston head in a single kit: the two components most frequently needing replacement on a heavily used GBB.
• Replacing the disconnector and its spring alongside the other parts avoids having to strip the replica again shortly afterwards.
