Nerf Gau-19

12 April 2020 - 08:01 PM

this is a long time project that has sat in my cad design phase for the better part of 6 years, with all the free time now applicable to me

i finally decided to bring the concept to life


this build is based on the real world Gau-19,

the reason i have chosen this is from the limitation of rotating air chambers adding extra chambers increases space by a lot, three barrels is the easiest to work with. 


this gun's internals for air chamber is based off the Nerf Long shot as dimensions are easy to attain online with out gutting my first edition, and working components are cheap and easy to effectively acquire. {springs,seals} 


this build features a unique brass breach Attached File  brass breach lower half.PNG   749.44KB   19 downloads


all components are 3d printed and designed in cad. Attached File  gau-19.PNG   327.09KB   19 downloads


this will be a DC powered device that uses air pressure to launch darts.


 a work in progress and this post is where i am at with the build so far.
