The new Tru-Site Super Slam uses a pin design with stainless steel tubing for even greater durability. Also includes a detachable bracket and an ultra-fine click adjustment for windage and elevation. The Super Slam has a tool-less design and a large circular field of view. The one piece head reduces vibration. The level is adjustable with two vertical bars. The level is also illuminated by a luminescent shooter's ring. The lighted models are designed to reduce unwanted pin glare. Also includes reversible bracket for greater vertical adjustability.
