The RAVIN TacHeads Bi-Pod gives you a stable rest when you need it. The spring-loaded mount attaches to any Picatinny rail with one hand. Just press and slide it on. Pull the release, and it pops right off. No tools, no hassle. This bi-pod works with any Ravin crossbow model that has a rail, plus other crossbows with standard Picatinny rails. The lightweight design won't throw off your balance or add much weight to your setup. When you're done shooting, it folds up small enough to slip into a pack pocket. Having a bi-pod makes a difference when you're trying to hold steady for that perfect aim. It takes the wobble out when you're winded from a stalk or holding on target waiting for game to turn. The legs adjust to uneven ground and lock solid. Built tough enough for all field conditions. The spring mechanism doesn't jam up with dirt or freeze in cold weather.
