hi ken , let me check on swapping turrets i know when you have warranty replacements they dont change them but since we are swapping used limbs i guess they could wear to the turret . resulting in a formation to the original turret . shouldnt be a problem just need to mark the turrets top and bottom. i will look at them , honestly i have naver took those off, shouldnt be difficult . i'll give you a call when i get them looked at. talk to ya soon , shane
