The MidwayUSA Reactive 12" Self-Adhesive Sight-In Targets make sighting-in your firearm easier. The bold yellow half-inch grid pattern and black background allow you to make adjustments. Hits on target are indicated with a white ring that are very visible even at a distance. If you ran out of staples or want to put up a new target just peel and stick the target to a MidwayUSA Cardboard Target Backer. Fits great inside the MidwayUSA Target Case Range Bag (994877).
