Hunting Rifle - Shooting + Shell Ejecting

I modeled the Hunting Rifle from Fortnite. This rifle is capable of shooting TOY bullets, shell ejecting, and has a bolt action feature.

I will lik here videos showcasing the gun and showing how to assemble it's pieces. 

The extra compontents required other than the 3d models are 3 rubber bands (+1 for every bullet) and a common Pilot pen spring. For it to work, the spring must have the following dimentions: D =  6mm, d = 4mm, L = 19mm. Insert the spring in the pause of the BoltUpdated model (it's plate already hase the pause integrated so just insert the spring and resume printing)

 

 

Boost MeI worked very hard on this model. It enclude many complicated parts. I would really appretiate if you could Boost this model so I will be able to provied more amazing models like this!
