Part of QOL Update 2/28/23, this new extension system introduced to the SPINE vr gun stock adds a greater level of comfort and customization.
 
The extension piece of the SPINE is the part where the Butt and the main stock body meet; the vertical piece with the SPINE icon engraved on the back. In the past we offered the SPINE in two different options (<5'10 & 5'11 and up) where the latter provided 2 inches of headroom for taller players. We're instead providing both options for all players to allow you to pick which height works best for you.
 
The extension now comes in 3 parts instead of 1.
Base: comes pre-installed onto the SPINE
Regular Insert: pictured in the middle and was the standard height of the SPINE
Large Insert: pictured on the far right, and adds 2 inches of height to the SPINE
 
The extension system uses binding screws to hold the inserts in place. When tightened on both sides with the included Allen keys, you'll be able to easily swap between the two inserts to find your most comfortable fit.
 
Along with the upgraded customization to the extension system, we also added a Swivel Sling Mount that can be installed on either side of the extension base. With this we've found 3 major improvements to the experience and usability of the SPINE:
More Sling Possibilities: With the sling sitting to the side of the stock instead of at the top, there is 0% chance any sling you'd like to use will end up blocking the view between your headset cameras and the tracking IR's on your controller.
Rotating Sling Mount: you're far less likely for the sling to get caught in a way that kinks or makes for an uncomfortable feel.
Comfortable Resting Position: When dropping your stock into the resting position, it falls to a comfortable position far more easily
