SPYDER VICTOR POWER PLENUM (35MM)

a Plenum featuring a volume of 2.279 cubic centimeters that fits as illustrated. We recommend the use of this plenum in tandem w/ the baby spring which together, bby our preliminary tests, produced an added 50 FPS on top of what the assault spring upgrade allows, though please take care when installing this otherwise very unsophisticated part, making sure that it does slip into the tube - you'll need to disassemble the marker, loosen the grub screw holding the valve in place, then ram both out w/ a .68 cal barrel maid.

The total length of the plenum is 35mm, is made from 6061 Aluminium and anodized.

The O-ring fitted is slightly oversized for the tube. We can supply this O-ring greased up on request.

Plenums carry no warranties, likewise making modifications to your SPYDER VICTOR will likely void your manufacturer's warranty.

The purpose of this part is basically to have a large body of ready gas in front of the valve, so that, for the split of a second that the valve opens, a larger volume of gas will be let through, instead of being throttled / bottlenecked by the gas line.

Note that your first shot may produce a lower muzzle velocity, but thereafter, the muzzle energy increase will be apparent in terms of a slightly louder shot report, the tiniest bit of recoiling force felt as well.

This will relieve you of the need to torque your ASSAULT SPRING in, as you can leave it untensioned. Tensioning said spring up will result in a loss of velocity.

Just to recap, we recommend the entirety of the power upgrade kit for the SPYDER VICTOR to maximize muzzle energy;

1. ASSAULT SPRING
2. EKO VALVE UPGRADE PIN
3. SPYDER VICTOR BABY SPRING (FOR PIN VALVE)
4. 35MM PLENUM
