Excellent reply David! Let me add a bit more to it. I can only speak on behalf or the HW,...haven't owned an AA rifle,....yet, but anyways. The HW90/RX series guns are actually a Theoben designed gun of the late 80' that Weihrauch liscenced out to manufacture. Probably so Beeman could offer a high end GasRam rifle. Just having the Theoben name stamped on the breech block is just plain COOL!!! One hole groups at 30 an up yards is doable all day long. But these rifles were designed as a pure hunting rifle. The only down-side I can think of with the 90/RX is the weight. They are a heavy weapon. Not barrel heavy,... just a stout feeling rifle. Besides the fact that it can be cocked for extended periods of time as David said, the thing that stands out the most to me is the resetable safety of the trigger group!!! There's no need to re-cock the rifle. Just depress the front tab and and you're good to go for a better shot. Noise level (shot cycle) is also a very desireable trait with these shooters,..... A simple 'pop' and that's it. No twang, buzz, no torque twist. You can also regulate the power to suit your taste with a pump. Good news is that PA will also have the pressure gauge available from Weihrauch in the near future!!!! A deffinate on my short list of AG accesories. For field use, I'd go with the HW90. For FT and paper the AA would probably be the better instrument. Best wishes on your new AG aquisition!!! tjk
