You really need to ,I have one on order a .22 fac

What you get
The gun so electric solonoids to open the low pressure air to open the spool valve and high pressure air that in turn closes the valve , dwell time low pressure and high pressure all adjustable
Adjustable lop ,butplate height
Programable fire option
One carbon fibre barrel approx an inch dia
One std liner one plus one thou oversize liner both Nickel boron coated , slippy as snot
Suppressor and sound moderator
Regs that will turn up and down under pressure without damage .
Hardcase
Barrel collar to further support the barrel
Tools spares kit grease
The two things I would change is the cocking lever locking back when open and something to mount a normal bipod on
