"Parts of this carrier looks as it were carved by a butternife and lots of tool marks. Only smooth parts are the round edges. Not as slick as my old carrier when it comes to comparrison of contact points. I believe i feel for hype. Havent shot yet but by my observations its okay but not for 250 w/ shipping."
