No Oring design for an air-tight perfect fit. The bolt is made from a nylon-like materaial and is light than even delrin. Velocity is increased due to less force required to move the bolt. The bolt has a cupped face to gently push the ball forward. No venturi producing higher flow. No oil. This bolt is self-lubricating like the delrin, but can take moisture and oils without swelling. Suggested Retail Price: $49.00
