Have an 8” 556 and have wondered about using my 5k AM on it.

Any guess on how long the can will last? Gun does have an frt in it.

I think a short brake like our minimalist brake isn’t a bad idea there.  I haven’t seen anything nickel 625x with enough wear to know where the wear life is.  I just know from our testing it exceeds the performance of 718 by a considerable margin.

There are carbides and work hardening and wear reducing materials there that do a really good job with wear, but in 8” and frt the application is a severe wear application meeting a very wear resistant alloy so its hard to predict.
