You will need 12 of these.just two green connectors attached by a white rod.
you need 4 long orange roods. attach a orange rod in the center of each yellow connector.then attach the greens as shown,one on top of the next one.
do the same thing you did with the first four greens, with the last 8, be sure to space them out a little.
this is one of the parts that needs to be modified,but...where ever theres a green connector hole,place a yellow rod through it with a single grey con...
next...add two single grey connector to each orange rod and put the yellow rod through the holes of the grey connector.
this needs lots of modifications...just a simple red rod with a orange connector on the side and end (does not need to be broken)

Now this is the extension of the barrel, so it can cross your shoulder, you will need 8 of those funly purple connectors, and slide them through the s...
next make this piece you need 2 wierd purple connectors, and 6 of the blue ones, if you have a better way of connecting them, be my guest...
Now just connect them!
you will need four of these. two white connectors and one white rod in the middle.

now connect the other piece the same way as the last one
now just insert a white rod in each of the pairs of holes and connect the middle so it won't fall out.
now place a bllue across each of the red corners, and connect an orange connector between the two red ones.then connect the end somehow
now attach those green /other connectors to the barrel of the gun like so.
this elastic you must need, it is essential to the design of the block trigger.you need to add the elastic so it will force the trigger down on the ba...
now, you can add however many elastics you please, but they must be balanced out! IF THE FORCE IS NOT EQUALLY DISTRIBUTED, MASS PADAMONIUM WILL OCCUR!...
