I didn't like the give in the Saber Tactical bipod rail, with the amount of give in the rail I know it couldn't be good for accuracy. I milled out a stiffener from some 5/8" aluminum, I used the 1/4 x 20 tripod screw hole for the rear and I drilled and tapped an 8/32 hole in the rail further out to attach the stiffener. When I got it installed, I can't see any movement or give when sitting it down on the bench with the bipod installed.....and it also works as a bag rider with the bipod off......
