"Mick-VA"Mine arrived last Fall shooting 901 fps for MK1 and 907 for MK2 JSB 34 gr. Yielding 61-62 FPE. Shoots 896 for 31 gr H&N Grizzlies which fly surprisingly well at least out to 120 yards (range limit). Grizzlies have more friction in the barrel but they noticeably drop much less over distance. 1st gun the grizzlies seem to shoot well in for my collection.
38 to 40 shots on reg filled to 250. Reg is set somewhere near 150 bar. AEAC YouTube channel has a great review on this gun with useful data.
Gun is very high quality and shoots exceedingly well but is not backyard friendly in my opinion unless you have at least 45 yards from your nearest neighbor. Mine has the CFOS offset moderator. The moderator is a reflex design but does not have baffling or damping material inside. Pretty much empty.
