This only works for older models of the Venom Pro. Newer ones shoot hotter. Please find the remix that brings the FPS down further below 120. 

Got a Venom Pro but it's shooting too hot for 130FPS? Fear not!

An insert for the Venom Pro which features a 20mm Straight PCAR (no angle) to reduce the FPS of the blaster from 125-135 FPS to an average of 120 (tested numbers in Photos). This file is just called “Venom PCAR below”, and there is also a STEP.

This fileset also includes a version with 25mm and 30mm of PCAR action in case you need FPS reduced slightly further. Note that I don't have specific numbers tied to these two lengths, but they will be lower than the FPS from the standard 20mm PCAR.

Increased ID is a 30mm PCAR with an increased ID in the barrel leading into the PCAR lines.

These PCARs are inserts rather than barrel replacements because I wanted these PCARs to be installable and removable without the need to take apart the blaster. However, converting the PCAR into a barrel replacement would be trivial so that may be coming soon.
