I switched out a couple of my AR handguard to Hogue overmold style , their little plastic wrench bout cut my finger off when it slipped and I ruined a bbl nut trying to use a belt friction wrench ,
My son in law works as a machinist and he made me a spud that slides down inside the bbl nut and then just use good bbl wrench on it ,, took me 5 minutes to switch out 3 of them with new nuts when got them ..
Should get a patent on it
