Cage
While the replacement cage is not necessary, the original cage is relatively low crush and did not seem to perform well with my darts (close to stock iirc). The replacement cage has 32.5mm spacing and is designed for Roboman automation Turbo Ranger Minis, though the wheel wells are 33.5mm diameter so any wheel that fits within that will likely work, so long as it fits over the motors mounts, which are 21.5mm wide. I'm not super familiar with this size class of wheels, but I believe this will be essentially anything that fits in a 32.5mm cage.
An alignment setting tool is included, and using it to install TR minis will leave them perfectly centered in the bore. An ejection tool is also included, which should work for any wheels.
The cage should be printed on the side that faces the magwell, as this will allow the integral pcar to print properly
Picatinny Rail
This part is not needed if you want to use the original tactical rail, but this allows for mounting of most red dot sights used in the hobby.
Installation Notes
The stock mag release spring can be reused
The pin for the mag release may be quite tight, so some force may be necessary during installation
Take care to install the pusher correctly, if it is installed too far forward while the trigger is released it will not be able to return properly
If you are replacing the stock batteries with a lipo, I recommend cutting out the battery portion of the battery tray
The motor screws can be recovered from the original cage
I recommend cutting out a portion of the shell so you can freely drop mags, shown below. trimming this to fit the contour of a talon mag should not impact the functionality of the blaster should you convert it back to N1 darts later
