The InnerlocÂ® Blood Bugâ„¢ is a lightweight broadhead made especially for small game hunting with air powered air rifles like the Umarex AirJavelin. It's a special folding fixed blade design developed for use on small game. Weighing only 50 grains it flies like a dart from pneumatic arrow guns shooting light weight arrows. The special design allows for the arrow to be pulled out of targets without much difficulty. Get this 3-pack in your cart and complete your order today.
