So the MPP is kinda long so I figured why not bullpup it? This kit includes a file set for the front mounted trigger, an over the shoulder style stock for a short setup and a full stock for larger batteries and longer builds. The kit does not require any mods to be done to the blaster or for it to be opened to install it. The files include both the STLs and projects for Orca slicer of each section with pre painted supports.

    Overall a great kit, with a couple flaws. It makes the MPP much more practical in CQB. Thank you for the free files! One recommendation:

    The trigger linkage included didn’t work for me, at least when printed in PETG. The M3 screw didn’t depress the trigger enough, and the linkages and braces flexed too much. I edited the files to make it use an M4 screw, and I made the braces wider (I extended them towards the front of the blaster). I widened the trigger plate track so that M4 nuts can fit in the track and guide the linkage bolt smoothly. This improved the trigger quite a bit. With a trigger return spring installed, the trigger pull is quite heavy, but less spongy than without the kit.

    Also, the area between the back of the grip and the magwell is a bit cramped for my hands. It’s comfortable enough with some padding, but moving the grip maybe only 5-10mm forward would help a lot. Otherwise this is a great kit! I also added a trigger guard and extended the front under-barrel picatinny for a grip / masterkey.
