Introduction: Double Shot Knex Pistol
This gun is based off of Big Z's H&K USP .40
it shoot 2 rounds at once mostly because i couldnt make it shoot one. so im taking a con and making it a pro :D
There should be more than enough pics to help u make it.
And this is NOT a double barrel gun.
I give Big Z 90% credit, please go check out his guns :)
