Hey Kenton sorry for the delay. Upon further inspection you'll need to make the following modifications to your blaster before we can move forward.
For level two certification (if applicable):
If using the Hasbro E11 toy blaster, it is modified to have the correct number of T-tracks (6 total), with a lower row of open vent holes on the magazine housing side. This is accomplished by covering the pre-existing rows of holes with T-tracks, then grinding off the lower integrated T-track on the magazine housing side, and drilling a new row of holes in its place.
Yours
