Got it as I wanted to change things out in my stryfe. After putting it in I have recognized little improvement to consistency. I am very selective on what darts I use so I didn't run into issue with length variability for darts, however the pusher does ensure darts get to flywheels quickly.
I ended up running into a problem with the pusher arm getting caught on official nerf brand magazines. The pusher rubs on magazine I was using from a regulator, I had also stripped the screw hole for the pice that connects the trigger to the pusher. The combination of these 2 problems resulted in the blaster having both the trigger and pusher in the backwards position. I had to take the blaster apart in order to fix the issue. I put in a longer screw to keep pieces tigh and will avoid using official nerf mags.
I bought this with every intention to use it but before I finished my build I decided to go one step further and install a full auto kit.
