These dies are used to clean up threads in flash hiders sound suppressors all sorts of things on the barrels AR15s and M16s. I love these because they last to what seems like forever. Say three or four years. and beleive me in a full team shop they they get the heck beat out of them. Still like the man said the take a licking and keep on ticking. I use them for chasing threads To building new cans for full auto barrels. Dang these things are great. no joke.

excellent product

Used this die with the centering guide and had excellent results, threading a mini 14 and a 10/22 barrel. It cut CLEAN SHARP threads and stayed sharp itself. I would purchase again.
