. it's the easiest way. later, get a tko stage 5 sound stopping device for less than $50 shipped (works great)....and whatever scope.. it takes about half as many pumps to refill to the 2000 psi mark as compared to the 3000 psi (marauder) mark. i've been using one since 2009 for hunting....maybe i just ended up with a REALLY good first run walnut disco, but i spent about $25 for the caliber change parts from crosman.com. i changed it to a .22 caliber. got a tko stage 5 device, and tuned it up a bit . now it gets around 25 shots at an avg of 840 fps with 13.5 jsb's , and 25 shots at 780 fps with the 16 grainer jsb's...... really feels like 'cheating' when i'm out hunting with this "poor man's pcp" , but it's a super-light (6.5 lb scoped), accurate as poop, silenced, 21 ftlb air rifle that's easy to reload..... and it'll be easy to get parts for the gun or pump here in the states. - paul.
