Description
CSR-SWRDFSH (A.K.A Canadian Space Rifle MK2)
IMPORTANT SAFETY INFORMATION!!: This is a toy that fires a projectile! Never fire at pets or unwilling participants. This can damage drywall and eyeballs, use caution and protective eyewear. Never brandish this as a real weapon or bring it out in public. Just because you know it's a toy, doesn't mean other people will. Make sure to check your local laws regarding replica firearms/ toy guns. Enjoy, be safe, and be smart!
The CSR-SWRDFSH is a bolt-action, magazine fed toy blaster with shell-ejection. Perfect for cosplay or indoor target shooting! It is fairly powerful so it shouldn't be used for battles with friends unless you are both wearing eye protection and long sleeves, as the printed projectiles can be painful on bare skin at close range. I am an Amateur designer who is still learning and seeking to improve, so I have included the .step files for all of the parts so any Talented or New designers to make changes and improvements as they see fit.
This is a reimagining of one of my earlier projects, the CSR-MK1, to make it even more sci-fi looking. It is inspired by both real and fictional firearms like the FAMAS, H&K SL18 and the BR75 Battle Rifle from the Halo Video game series. Although it is functionally the same as the CSR-MK1, I redesigned most of the frame parts and made some improvements to the internal mechanisms like the bolt.
BEFORE YOU START:
This is a moderately advanced project to print and build, it also requires additional non-printed hardware like screws, hexnuts, compression & extension springs. Operating it can be finnicky and requires a bit of practice and skill, so make sure you are up for a bit of a challenge before you start printing or ordering any parts. If you have built the CSR-MK1 or any of my other blasters, this should be an easy process for you.
