This is the toughest micro-adjustable target rest on the market today. It features our own design in launcher blades with a unique indexing system for changing out the launcher without having to re-adjust your tune. The launcher arm also rotates for blade angle. Laser-etched adjustment lines and oversized lock-down machine screws complete this rest. The Pro Blade comes with .008" and .010" standard width blades to help the Elite Target Shooter adjust the perfect tune. (.012" standard width & .008", .010" wide width blades sold separately)
