Great price !

Cutting the Correct thread or chasing threads that have been cross threaded . Was to use !

half the cost ten times the value

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.

Chinese junk

Hard to start thread squarely- dulled before completed the job

Doesn't fit clean muzzle threads

I purchased this to chase a damaged muzzle thread. I tried it first on 3, clean, threaded, muzzles from different manufacturers. It would attempt to cut threads immediately. These barrels have clean, tight, threads that fit several muzzle devices. I don't trust this die to cut threads for a suppressor mount.
