Great sight tool - LaserLyte Kryptonyte .50 BMG Green Laser Cartridge Bore Tool Fits Inside Chamber K-50

Upon first attempt the green laser didn't activate. My fault though. I let my M82A1 bolt group fall gently onto the back of the laser cartridge for fear of harming the laser. Forget that. Chamber the laser, pull the action back and let the bolt group do it's thing. It easily handled the impact. The laser comes on and works great. Bright bold green light easy to see down range. At the cost of .50 cal ammo, this saves alot of zero in cost. Typical of LaserLyte, it's an excellent product.
Pros: Solid quality, fit and finish. Works well with bolt and s/a actions. Saves money.
Cons: Pricey, but you get what you pay for.
