I have an early Sendero (before J-lock) 26" non fluted barrel. 300 Win. Mag. Has a sweet trigger that is crisp. I just had Dave Young install a JP tac muzzle brake
(side discharge and the crown can be cleaned with out removing brake) I am just getting ready to bed it back into the origional HS stock. I will sell it if you are interested.
PM me for more details.
