Does what it is supposed to do - Strike Industries Pistol Barrel Cover Thread Protector

I previously ordered a threaded barrel for my G19 gen3 glockoff build. It was a blem so it was super cheap and did not come with a thread protector. Obviously I don't want to leave the threads flapping in the breeze to get damaged. This little dude fit right on perfectly. It came with two rubber O-rings, one of them is a spare. It looks good and it is solid. Yes, you can order something off AMZN from a company you can't pronounce or you can support Strike Industries and Optics Planet and know you are getting a great product at a great price.
