Things I liked: The weight of the gun and the ease of pumping for your shots. The pellet magazine is a classic and works flawlessly (and are inexpensive). I also like the internal BB reservoir for shooting. The gun actually cycles the BBs really well. I am a fan of the iron sights on the gun as well--I could add a scope or red dot...but the gun just plain shoots well and is backyard friendly to boot. It's a nice spin on the pumpmaster type powerplant.
Things I would have changed: Not a thing--it is just a really fun gun to shoot and should last years!!
What others should know: Buy extra magazines and have a blast plinking in the backyard or at the range
