Project X Knex Rifle V2.

After a few weeks of moding and improving my original project x knex rifle i have finally finished with verstion 2. The version still uses the same concept of removable parts but ads a better barrle, a scope and a kind of stronger stock. It now shoots about 30 feet when you make the v2. It is about as accurate as every other knex gun on the site.
After the v2 is put togerther there are pics for the v3 mod. The v3 is yet better and improves on the firing pin, the barrle, and the mag pusher. The v3 shoots about 45 feet. Any ideas for improving to v4 i would love to hear them.
The pros and cons of the v3
Removable options.
Shoots a good distance
It is pretty strong
Inventive way of makeing removable options
Kind of feels comfortable depending on how big you are
It takes alot of parts
It is flimsy in some spots
Some parts need to be cut
Crappy trigger system

    cool gun but i cant seem to fit the magasine in, ive gone through everything again and again just wondering if you could put some more pics of that thanks

    just know that there wont be any mods for the gun. I took it apart and right now i am working on a full auto gun Some what like the mulcher in gears 2


    Thank you I know I have been sorta a pain with what to do, but thanks for helping me I fired the gun in my basement and it hit a picture hanging on the wall and it fell off.This gun is sweet,I rated it 5.0.


    it doesnt really matter how much of a pain you were. I am just glad that somebody made the gun and said how good it worked. Just know i take no responsibility for anything that you break or hurt with it


    pic 17 is the part that shoots up to push the block trigger out of the way. Think of it as a firing pin for the firing pin. Note that too also needs a rubber band to force it up


    I don't know where to put any rubberbands can you tell me, and sorry forteh message before I was a little upset.


    on the trigger part put a rubber band so that the orange half peice is being pulled forwards (Sorry i dont quite remember exactly) and for the firing pin put the rubber band from the back part of the firing pin forward as far as you want. Also i did respond to your message i asked what part for the rubber bands
