Alchemist shortened 70mm prime plunger for low FPS

Alternate plunger and ram mod for Alchemist which allows it to use shorter springs with a shorter prime, to hit lower FPS. Its meant for HvZ or other low-cap gameplay. 

IMPORTANT: In order for the ram to cycle correctly with this shorter prime, the tip of the ram needs to be shortened! 

See the photo below:

Also, drill a hole on the tip of the ram, or cut a slot on the tip, to prevent vacuum loading a dart into the plunger tube.

Info:

The prime is shortened from the normal 95mm on an Alchemist, down to 70mm with this new plunger and a shortened ram. This plunger is compatible with shorter springs than a normal Alchemist. I use 4" long springs.

FPS estimate & spring/barrel combo:

I used this kit at Maryland Mayhem 2024 to get my Alchemists down to 120 fps without much fuss.

I used a 4" long 788 spring and a 22cm long 13mmID chambered barrel to achieve 120 fps average with both of my personal Alchemists I brought to the event. 

A 22cm long 0.527"ID barrel should also work fine (0.527"ID is the standard for OutOfDarts and Silverfox Alchemist kits).

I also got a custom length barrel from Kuryaka to use with my shortened prime Alchemist build. It's Kuryaka's normal chambered, 13mmID barrel, but shortened to 22cm long, which just BARELY still reaches the barrel locking nut on Alchemist. Its so good!

Printing:

Follow the normal Alchemist print settings for the plunger components.
