Altra AA-SI-00003 Insert and Outsert, .166, 350 Spine, Silver, 12 Pack

The insert securely fastens into the arrow shaft at a depth of 0.875 inches, providing a stable and robust foundation. The outsert threads directly onto the insert, encapsulating the arrow's leading end at 0.43 inches for superior strength and longevity. This design delivers unmatched durability, making it ideal for intense archery sessions. Pre-installed rubber O-rings on the insert help lock the outsert in place, effectively reducing vibration during flight. These O-rings also improve concentricity between the outsert and insert, ensuring a more precise arrow setup. The overall system enhances down-range accuracy, giving archers a competitive edge in targeting.
