I've just upgraded to a LP400 Alu from my IZH46m - my first PCP!

I love my IZH46m but it's a Series 3 Landrover
compared to the
Audi A6 of the LP400 in terms of refinement.

Doesn't make me a better driver however!

Do I need to remove the air cylinder when I've finished shooting or can I leave it attached to the gun if I'm going to be shooting again in the next few days?
