That FX Revolution was broke more often than when it functioned. After the 3rd time, all within less than a tin of pellets and 1 years time, I demanded action by the Co that sold it to me, after all the warranty was going to expire.
The FX was reasonably accurate, that wasn't the problem, a semiauto should be reliable or why have one, right ?! Plus I hated how the trigger would push back on my finger when fired, that was not done well by FX at all.
I got most of the value out of the Revolution towards a Royale 400 which I've been very happy with, so I'm not picking on a brand.
Not saying the SK19 will be reliable, it hasn't been proven over time yet, we'll see, but right off my impression was positive of the rifle.
