Main Barrel

this is the tan lock barrel modded from the v1. It is connected directly to the under-barrel.
just 1 picture is all you should need for this. The second picture is the connection to the handle

3/4 Fake Barrel

its 3/4 fake because one of the barrel sections is dedicated to improving accuracy on the gun.
the part on the bottom is the front grip, you will need that to support the gun

this is an auto-loading jam free mag that holds 15 shots and can be expanded to hold more unlike v1. The mag is removable, but i never remove it when i reload, i remove it when i mod the gun.
the mag looks bigger than the picture makes it look, doesnt it?
NOTE- The top section does not have white rods connecting the width to the depth of the mag, as they keep the mag from being inserted in the gun. The bottom of the mag is the part which hooks up to the under-barrel, via the white rods there. DO NOT INSERT THE MAG IN UPSIDE-DOWN!
the final picture is the hookup to the under-barrel.

you should have the front barrel in one part, and the stock and handle should be together.
the last picture is the assembly of both of the parts

this is the sight for the gun, it is fully optional, it just improves the look, and gives a good grip on the carrying handle.
picture 1 is the sight, picture 2-3 is the connection.

this is my removable bipod for the gun. It was made for show purposes, not recommended for sniping as it will break under a little pressure.
sorry it is not foldable, but i dont think i can make it foldable at 5 layers, and at least its removable...............
1. the bipod. who would have guessed?
2. the base attached to the foregrip.
3. attach bipod

Rubberbands, Loading and Firing

the pictures show where to hook up the rubberbands for their respective parts (pusher, pin, and trigger).
1. hook up the true trigger
2. hook up the ram
3. hook up the pusher
to fire, first take the pusher out of the mag, and insert blue rods. when you have replaced the pusher, pull the firing pin back behind the trigger (full drawback), aim, and fire. Unlike the v1, you dont have to turn a knob on the mag, its auto-loading!!!!!!!!!
4 things you can do at this point:
1. HAVE FUN!!!!!!!!!!
2. continue to step 11
3. comment
4. RATE THIS IBLE 5 STARS!!!!!!!!!!! (I say 5 because some jerk keeps making fake accounts to rate this ible 0.5, this used to be a 3.95)

ok guys, this is for the people who built v1, but are reluctant about upgrading to v2, because they dont want to work:
