Things I liked:Fit and finish are great. A solid weapon, nothing rattles or squeaks. Amazing power. I have the .177 cal. When using PBA pellets, pushing 1500 fps chrono'd. The stock scope is very capable. Things I would have changed:The report is stout. My neighbor thought i was shooting my .223 blot action in the backyard. First shot made me jump. This thing is loud! What others should know:Loud! PBA pellets are extremely lightweight and can be seen tumbling and corkscrewing past 40 feet by spotters as they create a supersonic shock wave. Use heavy ammo for the accuracy. Whatever you hit will be destroyed. This rifle is able to penetrate a 1 1/2 inch phonebook, a 2 inch thick cooler wall, and go 1 inch into a railroad tie in the same shot! Not a toy, mistakes could be lethal. Be safe. Have fun.
