I have got a client that is wanting to customize an old 110 in 7 Rem mag. He really wants to go with a chasis system and likes the MDT the best. Looking online at multiple chasis they claim they fit 110 long action but there is no mention of staggered or center feed, flat back or round back like most standard stocks specify. My question is, does anyone make a chasis system for this action or will one of the long action options available work fine? Thanks for the help.
