I'm looking at placing a Defiance Ruckus with a Bartlein M24 contour barrel in a T4A-TEAM w/ MCS2 stock that currently has a Proof Sendero inlet. I've heard that the Proof Sendero contour is very similar to an M24 profile. I'd prefer to use a Bartlein M24 in this stock and wonder if it will work without modification given that the Bartlein is a straight taper instead of stepped like the Proof is.
