This is a must have to protect the threads on your new barrel (Perfect fit).Alway happy with my purchases... Thanks!!!

Guys just spend the 15 bucks and get this thing. Fit and finish match their barrels perfectly. Do you really wanna trash the threads on your new barrel just because you wanted to save the cost of a 12 pack?? It only takes one "oops" to ruin those threads..

Great finish, very "close" fit. First one I received was difficult to get threads engaged so I requested a replacement. It was also very tight so I checked threads with measuring tools and they were correct. Used some threading oil and worked it onto the barrel with the nut wrapped in a shop rag and a pair of pliers. Got the nut installed and it looks great. Still a bit tight but that is OK, pretty sure you don't want this thing falling off in the middle of a good burst.

Part is perfect, shipping is perfect love these guys

nice fit and finish, ran two 32 round clips through it with no problems. good to go. THANK YOU.. P.S thread protector is nice too, looks good, great fit.
