Upgrade your plain old Sledgefire to a "Ultimate Sledgfire".  This 3d printed 'Sledgefire Singled Shell' uses 17/32 brass tube as a single barrel, resulting in a huge jump in dart velocity using a decent upgrade spring.  The Shell utilizes the existing rubber seal and holds the 'air restrictor' open, so there is very little modification to be performed.  We have seen slight increases in performance when the air restrictor is removed, it is up to the end user if they wish to do this.  Make sure that the existing rubber seal is not damaged. 

What you will need:

• This BlasterTECH 3d printed Sledgefire Singled Shell
• 150mm length of 17/32 brass tube (comes in 300mm length. (You can make 2x Slegefires))
• C836 spring (or another upgrade spring of your choice)

With this setup, expect velocities of 140-150fps with short darts.

The 17/32 brass tube can be set at different depths inside the Shell.  For example if you are using full length darts, you will need to set the tube lower to enable a full length dart to push in.  Short darts you can set the tube high up and close to the top of shell (see picture).  You may need to glue the tube in the shell to ensure no movement.

This product is designed / printed / stocked in house and can be dispatched ASAP.
