Is this kit compatible with my Gen 5 Glock?
No, this standard UPK is designed for Glock generations 1 through 4. Gen 5 models utilize a different, ambidextrous slide stop lever spring and an updated extractor design. Please ensure you select the correct generation-specific kit for your firearm to guarantee proper fit and function.
Does this kit include sights or a barrel?
No, this is an internal parts kit only. It contains all the small components that reside inside your slide, such as the extractor, safety plunger, springs, and channel liner. You will need to source your slide, barrel, recoil spring assembly, and sights separately to complete your upper assembly.
Are the parts made in the USA?
Yes, all components in the UPK-STD-GLK are precision manufactured in the United States from high-quality materials. They are held to strict quality control standards to ensure they meet or exceed OEM specifications for durability and reliable performance.
Do I need special tools to install this kit?
While a basic punch set and armorer’s block are highly recommended, installation can be performed with careful attention using common tools. The most specialized item needed is a firing pin channel liner installation tool, which is inexpensive and crucial for properly seating the polymer liner without damage.
