I though this was interesting and wanted to share it. Last weekend I was shooting my IMI Galil 7.62 ARM at a 100 yard target and thought I'd do a comparison of how the ARM built-in bipod affected point of aim and accuracy at 100 yards. I sighted the gun in on a sand-bag rest (no bipod) using FN ammo dated 1982. I was consistently putting 5 rounds in the center of the target with about 3 inch groups (using stock iron sights). When deploying the bipod which is attached to the barrel at the front sight area, the group point of impact raised about 10 inches and the groups opened up to about 6 inches.
The point I'm trying to make is that you can't use a bipod of this type for accurate shooting unless the bipod is attached to something other than the barrel. The ARM type bipod which is attached to the barrel is intended for using the rifle in a light-machinegun role.
