Part is acceptable for most applications. Since I already had a perfect unit from DSA and another from Young Manufacturing, I cut the rod off, resurfaced the slot, and use it for FAL Paratrooper Model folding butstock screws. The gas regulator wrench is of simple construction and performed fine. It conforms to the FN specification of 2.3mm tooth, although the handle construction is greatly simplified. The bush should be removed with heat and a heavy punch struck downward in a counterclockwise direction.
Part performs as advertised.
The front sight tool is unique. The tool fits all three sights well. I'd like to see the T-handle made larger with the ends cut into screwdriver blades for the rear sight. I'd like to see a method for attaching it to a hook or dummy cord. I'd like to see the square broach a bit deeper to grip more of the sight.
