Our New Gen2 Target Focus Trainer for your Holosun 507 Comp Optic. 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. Also retains the battery tray screw for added security.
The SBGW Target Focus Trainer™ is perfect for shooting in adverse conditions! No more tape for the sun washing out your dot.
Shooting directly into the sun, or shooting in the rain, the Stonebridge Gunworks Target Focus Trainer truly blacks out your optic for these shooting conditions.
