I think you’ll find the 1.25” much less picky…I have a V360 and a 1.25” Krieger MCR now can’t wait to get it and do a little testing myself.
FYI that stock is Fn awesome!! Can you say how much it was?
I have multiple 1.25" barrels along with M24's for my RimX. Both have been tack drivers... I didn't find 1.25 or M24 being more or less picky. I found the higher end barrels were less picky than the lower end barrels.
Stock is definitely awesome. It's a work of art. Randy charges $899.99 + shipping for his 2500x stocks bedded and ready to go. They are custom ordered so you tell him what you want and he custom makes each one.
