Is there any forum user who has had the opportunity to see and try the new Crown MKII? It is much more powerful than the crown I own, all to the advantage of power and, perhaps, precision. Now the slugs may already be used "out of box". It seems to have a larger internal plenum (about 20% more regulated air) and a 6.5mm valve ... all of which translates into more power, ranging from 20 to, almost, 30 J more, per second of the caliber. mmhttps: //fxairguns.com/rifles/the-crown/
