This Thread Protector 1/2 x 28 in Radio Active Green is a functional and highly visible accessory for your pistol’s muzzle.

Its standout color provides a unique visual accent, making it one of the most distinctive Glock parts for personalizing your build. Miami Shooters Supply ensures you get this quality component with our reliable, fast shipping.

FAQ
Will this fit my factory Glock barrel?
No, factory Glock barrels are not threaded. This is a Glock part designed for aftermarket threaded barrels specifically cut with a 1/2×28 thread pattern.
Is the finish durable?
Yes. The Radio Active Green color is applied using Cerakote ceramic coating, which is highly resistant to chipping, chemicals, and wear, making it far more durable than standard paint or anodizing.
