Things I liked: I bought this gun to shoot benchrest competition. It is about one-half to one-third the cost of other guns that are competitive in the Light Varmint class (12 fpe) for WRABF/USARB benchrest, shooting at 25 meters outdoors and 25 yards indoors.
Things I would have changed: The Air Arms T-Bar fill valve sucks, especially when it is cold. Getting the fitting on and off the gun is a real PITA. I have ordered a kit from Best Fittings Ltd, in England, to change the valve to a foster quick detach type. I am pretty tall, so the stock length of pull is way too short for me for position shooting, but not so much of a problem for shooting from benchrests. I would need to get some sort of after market extender to shoot Field Target with it.
What others should know: The gun is a little "pellet picky", at least for hitting a 10 ring that is less than half the diameter of a .177 pellet. It doesn't seem to group any wadcutters very well(of which I have 10'000). I have found that several Air Arms, or the pretty much identical JSB Exact, domed pellets, seem to shoot well. With a little patience, the trigger can be adjusted down to practically nothing, which is great for BR, but possibly not so much for FT. Overall, I am quite pleased with the gun and think it is a great value for the money.
Things I liked: Sampler Pack are a very good concept. They are a relatively inexpensive way to test various pellets and not have a few thousand sitting around, that you can't use, afterwards.
Things I would have changed: Rather than having only three pellets with different head sizes, I would rather see a broader range of pellets of one size. My gun doesn't seem to be sensitive to a .01mm head size change.
What others should know: For whatever reason, non of these pellets grouped well in my AA S400 MPR FT.
