Alot of fields arnt gonna let you run your hpa sniper because your fps is so easily adjustable. You are not a well known player, i assume, so therefore are subject to some strict rules depending where u play.
I dont even bring my gas sniper out as the line for misunderstanding is easily crossed, a he said she felt argument coud have a bad outcome. Also whats your hunting skil like? Can you accuratley range find?
Now im not raining on your parade, just a heads up before you dump money into the rig.
And check ebay for used pb equip its readily avl, and cheap.
