"Bought this gun off a friend, so far no complaints here! The only two cons I've noticed is the stock seems to stick a bit for me, and the gun will occasionally have feeding issues. This is solved however, by switching to full auto and shooting a few bb's and then switching back to semi. Otherwise a good gun. Friend chrono'd it shooting 430 fps out of the box and I chrono'd at 400 fps on a lower-charged battery after about a year since purchase. For the price seems like a good buy if they go on sale again.

"This gun is an amazing starter AEG, especially for the price. This out ranges my friend's LT-20B M82 and has amazing accuracy and reliability. This does jam occasionally, but only when you spam the trigger on semi. When it does, just fire it on full auto and that fixes the problem. I found the average FPS to be around 430-440. The grip molded into the mag well comes in handy, too. I find this grip better than any other RIS fore grip. While most of the gun is polymer, it does have a metal outer barrel, inner barrel, and gearbox.
