For target focus training for your HOLOSUN 509T. Blocks all light from coming into the front of the optic, this leaves a perfect theater for your red dot to appear consistent in any lighting conditions.
Our Patent Pending one-sided red dot covers are molded from Kydex that snaps to the front of the optic and stays on during live fire.
The SBGW Target Focus Trainer™ is perfect for shooting in adverse conditions! No more tape for the sun washing out your dot. Set your optic to a crisp brightness, no more bursting!
