Yeah, that too. Great for a hunting rifle. Is that a Titan in your avatar? The Titan is one of the rifles I'm considering for my purchase.
For my money, a tuned spring powered rifle shoots just as good as a gas piston rifle (at least they shoot as good as i can). Maybe the absence of torque and spring vibration helps a little, but I don't see that much difference. For me, being able to leave it cocked for hours while hunting is the biggest advantage that gas pistons have over steel springs. Also, the gas pistions are cleaner to work on.
