Things I liked:I like the quality of this rifle. I like the feel and balance of it. It is easy to charge and the fact that is automatically sets the safety on is a good feature. The fiber optic sigths that come with the rifle are of good quality and adjust very simply, not a problem sighting them in. The rifle is relatively quiet for the power it has. Using the H&N Baracuda HP 10.34 grain pellets I could shoot all day on the bench at 30 yards and cover them all with a quarter. Things I would have changed:The fact that the barrel brakes throuh the forearm makes it quite dificult to add sling mounts but it would be nice if something was engineered to do this. The rifle does get quite uncomfortable,as any rifle would, if you are trying to walk and carry it for long distances like I do. Other than that I am more than satisfied with this rifle. What others should know:I have no experience with the 22 caliber so I had a hard time deciding which caliber to purchase. I went with the .177. I purchased the UTG #DNO34 scope elevation compensator mount and a UTG 3-9 x 50mm full size tactical optic scope with the 1" tube. I got the Weaver low profile four screw rings. This worked out really well except I had to put a .010 piece of shim stock under the front scope ring so I could get enough scope adjustment. This worked out really well for the first say 50 shots then the rifle became inaccurate. I found that because of the heavy vibration when fired the ring caps came loose. I applied some liquid rubber on the threads and remounted the caps and resighted the rifle and it seems to be holding good to this point after about 200 shots. The scope is very nice for the price. I just put it on 9 power and leave it there. With the AO feature you can focus on anything from really close to far away. Scope caps get in the way if you are focusing really close, they touch the side of the barrel. As for pellets, I purchased the variety pack with the different pints and weights. I found that the Meisterkugein 8.2 grain shot very accurate at 20 yards they averaged around 850 fps with my rifle. The others like the RWS Super HP 6.9 grain shot an average of 940 fps but weren't as accurate. The most accurate at 30 yards was the H&N Baracuda HP 10.34 grain at 740 fps. I like the accuracy but now I wonder if I should have purchased the .22 caliber in stead.?
