Looking at purchasing a new CZ 457. Looking at the AT-One mounted in the Boyd’s And the VPT MTR mounted in the Manners stock with the adjustable cheek weld. Obviously there is a price difference… but does anyone have experience with either of these or both? Pros and cons? Major and minor differences (other than one is laminated and the other is composite)? Are both easy barrel swaps? Any info would be great!
