Things I liked: Price, simplicity, quietness,balance, robust construction, accuracy, velocity, rear sight.
Things I would have changed: At this price, nothing. I expected it would need tuning to perform to its potential.
What others should know: After initial firing and rear sight adjustment, I disassembled the gun and polished the bearing surfaces of the trigger/sear group, disassembled and lubricated the rear sight, and lubed all internal parts. The trigger pull went from very rough to a light 2-stage pull with crisp and consistent letoff - a world of improvement. It is really enjoyable to shoot now.
