Verified Purchase

Things I liked: There are a lot of things to like about this pistol. The look and feel are great. It is hefty like it should be. The accuracy is very good using quality bbs. The rear sight is adjustable for windage and elevation. It functions very well, is consistent, and feels very smooth. The blowback action is snappy.

Things I would have changed: The adjustable rear sight is just a tiny bit more rearward than I would prefer, so it is slightly in the way of my normal thumb motion to cock the hammer. Nothing too serious, especially on an airsoft pistol with so many other good qualities at a great price.

What others should know: Tonight I shot it over the chrono with a fresh CO2 cartridge, in my garage, with the air and CO2 temperature at 67 degrees. Using .2g BBs it shot 369 fps to 361 fps for 6 rounds. Using .25g BBs it shot at 330 fps.

Things I liked: I purchased this gun for basement plinking.... and I love it! The high-capacity 31 round magazine is great! I also purchased the optional "green gas" magazine for it. I like that one the best of all! It does not exhibit the chilling effect of the gas and the reduction in FPS that you see from a CO2 cartridge. I also purchased a Mad Bull Propane version 2 adapter that attaches to a standard 1lb propane tank .and refill it with that for cheaper refills

Things I would have changed: Nothing.....
