KENBEV if your brech plug has 2 small holes ,<one on each side of the nipple> its a screw in plug....if no holes just a nipple then its a push in plug with ...o...rings and it just pushes out.........please remeber that if you have a misfire that IF IF YOU WERE TO OPEN THE ACTION AND THE GUN WENT OFF THAT THE BRECH PLUG WOULD HIT YOU RIGHT IN THE FACE,,,,,,,,,DO I NEED TO REPEAT THAT i didnt think so ....if the gun fails to fire then just point in safe derection and wait.......the key problem i had wiTh these was keeping the nipple clean,i used PIPE CLEANERS OFTEN......JB
