Machined steel flip up sight set for your Grand Power Stribog SP9A1/A2/A3. This is a great drop in upgrade for the original molded plastic sights. Not only are the steel sights much more durable than the molded sights, the front sight in this set is also adjustable for elevation. These are factory sights manufactured by Grand Power in Slovakia. They include new steel detents and a elevation adjustment tool for the front sight.
