Just like it's big brother the Impulse Slik Shot, the Nerve Slik Shot is made with performance in mind.
These shafts have a special molecular bonded coating which decrease the coefficient of drag to .03 The coating will not rub off.
The shaft diameter sizes and O-ring groove have been slightly resized to reduce even more unwanted friction.
The surface finish is ultra smooth. O-ring contact surface is a smooth 6-7ui finish.
*Comes with O-ring and instructions..
The New Designz Nerve Custom Hammer Shaft is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
