Things I liked:Just what I've been looking for. Things I would have changed:Include wrench to remove locking screw. What others should know:All 3/8" rails on my air rifles have rounded crowns, The UTG 3/8" slot is flat and an "iffy" fit.
Things I liked:If the whole batch was a good as the best half these would be really good. Things I would have changed:Improve quality control. What others should know:Size seems to be highly variable. I can feel obvious differences when seating the pellets. The looser fits even tumble and hit the target sideways. The tighter fits are very accurate.
Things I liked:Having shot my old Chrony, It's comforting to have some protection availablefor its relacement Things I would have changed:More standoff in front, provision to mount from the bottom. Use a different material that is transparent to the LED lights from the lighting attachment. What others should know:Only usable outdoors. The plastic material blocks the light from the LED lighting attachment indoors.
