Hi, I am the one who made it :)
Any questions, just ask.
I have had a few of these guns for about a year now, and want to share it with Nerf/LEGO community now that i have finished university.
the concept came from the barricade, and wanted to modify but i didn't want to damage it (as it was a present from a friend).
so i started prototyping with Lego, using a failed dart reloader as the base (as it fit the cartridges perfectly)
well, to cut a long story short here are the results, see what you think
it can also be easily disassembled for transport.

A closer look at the internal mechanics of the gun can be seen here.

Sturdy in battle, no bits drop off when being handled roughly
the parts are not glued in any way, only 3 switches are glued to a few bricks.
firing push rod always resets itself to quickly fire the next shot, whilst eliminating misfiring
light enough to duel wield. (the club i was in stopped me doing so, as i consistently owned them with it) :lol:
