Harris bipod l series - Harris Engineering Model L Series S 9-12 Bipod LS

I installed the bipod on an AR15 and took the gun to the range. The bipod worked exactly as it was supposed to. It has unlimited adjustments from 9 to 12 inches. It fits onto the sling swivel and tightens up with a knob instead of the old design where you had to use a screwdriver or coin. I would recommend the product to anyone that is shooting off of a bench or prone in the field.
