The BAMP Pistol

Introduction: The BAMP Pistol

This is my first instructable so please go easy on my.

The BAMP (bolt action magazine pistol) MK1 is a small, piece efficient, knex magazine pistol.


Decent range

Low jam rate

Effective magazine with 8 bullets or less

Piece efficient


Jams with more than 8 bullets

Could have better range

Trigger sometimes falls out of place

    Yeah I know it is not the best gun but it is meant to be for people that don't have much knex. I can make much better guns. Just about to make a rifle now. Thanks for feedback though :)
