Good Glock upper


Bought a G26 gen3 upper back on the Black Friday weekend and got a $50 discount which was a plus.
Came to my house in a decent amount of time. As far as the upper goes it’s decent, it’s a factory G26 upper. Not much more to say other than that.
Good OEM upper at a decent price!

G33 upper = Thumbs up


Bought a G33 upper and arrived looking great. Fit right on like a Glove and functioned great. Thanks GlockStore for having a Great selection on all Glock OEM parts. Will be shopping with you again.
