I've got this airsoft pistol laying around that hasn't been used in 3 years. It has something wrong with it that stops it from blowing back after every shot like it's supposed to do. I think the slider spring is the culprit but I might bring it in today to see if this shop can fix it. It is a hop-up version meaning it shoots at around 300 fps if I can remember correctly, although I lost the box. I still have the original manual with all of it's japanese? characters, but the pictures are very helpful in disassembling the gun if you want to fix it yourself. The magazine uses green gas and holds lots of bbs, I think ~20 or so. It's a heavy gun but has a plastic outer frame, as opposed to a metal frame. It still weighs ~5lbs or so, making it feel realistic and comfortable to hold. The handle has smooth contours for your fingers as well which makes it really comfortable (the most comfortable pistol I've ever held). Looking for $45+shipping if I don't fix it, and if I can fix it, $70+shipping. Here are some pictures.
