Rear insert for arrows used in Man Kung crossbows

Rear insert for arrows used in Man Kung crossbows, as well as those from other manufacturers; designed primarily for carbon arrows. The insert’s outer diameter is approximately 7.5 mm, while the outer diameter of the carbon arrow for which the insert is intended is approximately 8.8 mm. The inserts must be inspected and replaced immediately if struck by another arrow. A shot insert with a sharp edge can easily damage or cut the xbowstring, which can lead to fatal damage to the xbowstring, limbs, or cams of the crossbow. Having spare arrow inserts is a must for every serious crossbow shooter. Price is for 10 pieces
