"The OSP gun mounting system allows for a very fluid, efficient acquisition of target. As a snap shooter of ruffed grouse, I noticed that the butt of my gun was coming up quicker than the front. After being schooled on the gun mount through the OSP flashlight drill, my gun comes up very fluid with no wasted movement. This improves the number of birds in the field killed. I highly recommend their system."
