These reactive targets provide instant feedback, leaving no doubt as to where your rounds have impacted the vital organs. The vital organs are made of environmentally safe, highly visible gel. This 100+ round target was developed for most calibers. Developed with a Navy SEAL, the targets are ideal for defensive training, but are also great for a fun day on the range. Each organ is represented by a different color, providing easy-to-identify round placement. The water-soluble gel will not stain clothing. Additional grid targets are located in the corners to maximize use of this fully reactive target.
