Things I liked: Excellent quality overall. Looks great, action is fast and reliable. Recoil action is perfect. Spittin image of the real thing.
Things I would have changed: My only wish is that the gas strage tank was larger. I get about 16 to 18 shots from a green gas charge. I only load 7 rounds in the clip at a time to simulate the real thing in combat action. I get two 7 shot fills and maybe 1 or 2 more shots before I have to charge ti again. This is more a matter of the size of the clip/tank. It is accurate to the real thing so the tank is very small. This is really a minor complaint.
What others should know: Get it, you'll like it!
Things I liked: Works as it should. Can't tell the difference from the one that came with the pistol.
Things I would have changed: It holds about 17 or 18 shots worth of gas. Holds about 25 rounds, so it can't shoot the whole clip out. Since we hold to authentic capacities, I can only load 7 rounds at a time while acting. So the amount of gas it holds is not a big thing, but it would be great if it held enough for 21 rounds or 3 loadings.
