BUMP45 - Toy Blaster Mô Phỏng Thật (Realistic Toy Blaster)

THE BUMP45 - Realistic Toy Blaster

This is a toy that fires a projectile! Never brandish this as a real weapon or bring it out in public, this is a toy modeled off of a REAL LIFE firearm, treat it as such. Just because you know it's a toy, doesn't mean other people will. Enjoy, be safe, and be smart!

(I am waiting on some hardware so I can upload a build video, but everything seems to work well with my tests. I will upload a build guide, STL's and more info once the parts arrive but for now I have just included the .Step files.)

My most impressive blaster/launcher yet, now featuring realistic shell ejection and medium launching power! Perfect for shooting cans or targets and amazing your friends with the realistic action. Based on the H&K UMP45, I tried to keep the look as accurate as possible, but for simplicities sake I omitted a couple features.
