Midway sells a barrel switch kit I believe.. Don't have their catalog here but the 110 is fairly easy to switch.. Not to intrude but I am very curious.. How did he 'blow up' the 110.. Pictures would be great... Thanks for the reply... Be aware, any barrel will have to be fitted to your rifle..this is a job that on a 110, CAN be handled by an ADVANCED ameture but with care please.. Head space set improperly is a diaster!!! Thanks from the gunnut69
