Airsoft homemade DIY 3D printed HPA sniper rifle BiG-no HPA engine, no batteries

I have to mention that after testing on the field the second version I concluded that the 250psi that I used in chrono test is to much resulting in dropping range and accuracy. I recommend around 130psi instead.

----------------------------

Here's a build that proves you don't need any fancy HPA engine or batteries to make a HPA sniper rifle that performes the same as any expensive one and is extremely silent.
