There is a sniper style which has a gradual bend and much longer turned down handle than I need. The ATI bolt on style is a nearly flat 90 degree straight down bolt handle. The ATI is designed to be out of the way of any scope you would use.I'm curious of what exactly he is looking for as I own one myself and have a problem when trying to eject the shell casings it hits my scope & is a pain in the ass. What exactly does the finished product of a turndown look like I guess is what I'm asking & does it remedy that problem??
