FLASH SUPPRESSOR TAP FOR AR-15/M16 & AR-308 Reviews & Ratings
Not a bottoming tap
As this product is billed specifically as an AR-15/M16 flash suppressor tap, it should be a bottoming tap that has full threads almost down to the very end of the tap in order to cut threads right down to the shoulder of the flash suppressor. This tap is a plug tap, with the last few threads being tapered. I bought this tap to clean up damaged threads in an existing GI surplus flash hider, but it couldn't clean up the bottom-most threads because of the taper. As a tap for cutting new threads it would be fine, but would need to be followed up with a true bottoming tap for this application.
