Carbon Fiber Bolt

$49.00

A lightweight carbon fiber bolt for the Autococker, designed and tuned specifically for the stock valve and stock transfer tube port. It took close to 100 designs to get here, with the final 25 put through six rounds of chrono testing. On a stock valve, it posted the highest average velocity of every bolt we tested.

Design Features

Slanted Mid O-Ring: Enlarges the inlet port and gives more dwell time for a fuller, more efficient shot.
Trimmed Contact Surfaces: Less drag in the body for a smoother, faster cycle.
Standard Seals: Uses standard #12 urethane o-rings, easy to find and replace.
Tuned For Stock: Built for the stock valve and stock transfer tube port.

Test Results

Every bolt was shot through the same marker, stock valve and air setup.
