Allen Company X-Ring Black Steel Rifle and Shotgun Scope Accessory

Get your scope aligned without wasting ammunition. The Allen Company X-Ring Boresighter uses a laser dot to help you align your scope or sights with the barrel before you ever fire a shot. This cuts your sight-in time dramatically and makes the process far more efficient. The positive on/off switch preserves battery life between uses. The value pack comes complete with a battery and mounting screws for immediate assembly. Sized to fit .177 to .50 caliber rifles, or 12 and 20-gauge shotguns.
