8×8″ square of 3/8″ thick laser cut AR500. Two square holes for mounting via a carriage bolt, and fits perfectly on both our T-Post and Enhanced T-Post Mounts. Can be mounted either as a square or a diamond Orders of up to 70lbs ship with a single flat rate price. ALWAYS keep in mind impact velocity and energy prevent target damage. Keep your impact energy around 2500 ft-lbs for 3/8″ thick AR500, and 2750fps or under to prevent pitting of the target. If shooting with pistols under 100 yards, we recommend shooting the side without etching to prevent the slim possibility of a ricochet. We use only mill-certified AR500 for our targets!
