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.

Firing demo

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

Lego parts list

http://www.mediafire.com/?9d6q84zmdg945cc

Extra Non-LEGO parts required

2x micro switches (maplin code GW67X)

1x micro on/off switch (maplin code FF77J)

1x micro DPDT 12 relay (maplin code N04AW)

2x Li-Po battery pack around 7.4v or 4x 14500(AA) Li-po Cells.

3 blobs of Gorilla glue.

Wire out of a telephone/network cable.

Range: over 15 meters

ROF: 35 darts in 17 seconds

Lithium Ion powered (14.8v 850Mah) lasts about 8 Hours of use

Volume is less than the Nerf Barricade

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:
