Sniper rifle that implants GPS

Interesting looking. It's not the same as targeting with GPS (which is what Saito's gun/hawkeye does), that gun puts a GPS tracker chip in the round to track the target. It's useful for tracking animals you don't bring down first time and making sure you get em dead, hunting is animal cruelty if you are too negligent to make sure you kill the animal properly, after all.
