RPM Bowfishing Black Mamba Arrow with NOS Point -The entire line of RPM bowfishing arrows features the All Point System (APS) and a true 5/16-inch skinny nock. The result is a collection of bowfishing equipment like no other. The APS incorporates a universal ferrule onto each shaft, thus allowing the shafts and points to be switched and swapped within seconds without the use of tools.Every point in the APS sports a hardened conical "bullet" tip. Bullet/conical tips eliminate the planing that sometimes occurs with traditional chisel style tips, and No Plane means Better Accuracy. Rocks? Not a problem for these tips. Each APS point features either a single or double (dual) friction ring designed to both secure the tip and body to the ferrule, as well as to prevent spin-offs when targeting larger fish. Hardened bullet tip resists deformationDual friction rings for secure attachment and easy three-twist releaseTwin serrated gripper barbsHalf inch shorter than similarly styled points
