I've had most of the popular Chinese rifles and like I said earlier when they where cheap they where worth buying as you had a lot bit of wiggle room cost wise to tune them before they become the same price as a new 95 but would be slightly better because of the tuning done than the out of the box 95, I had a secondhand tuned XS20 once which had been fettled by Venoman and although it was damn good (and a bargain may I add) when I did a swap for a HW95 with another rifle comparing the XS20 and the 95 which had a drop in V-mach kit, you could certainly tell the quality difference, although they shot pretty much the same, the 95 was just silky smooth to cock and just felt 'tighter' than the 20, which had this graunchyness to it.
