FAQ
Will this thread protector fit my factory Glock barrel?
No, it will not. This is a Glock part for aftermarket barrels only. Factory Glock barrels are not threaded; you must have a dedicated threaded barrel installed to use this protector.
Does it come with an O-ring or crush washer?
Typically, thread protectors of this style do not include an O-ring. They are designed to be hand-tightened securely against the barrel shoulder. The knurling provides the grip needed to achieve a snug, secure fit without tools.
