"This gun has a plastic exterior, the only metal parts visible are the trigger, safety switch, and barrel. The internals are all metal. This gun has a 7 round magazine not 10. The trigger pull is a bit hard (around 10 lbs); the suppressor does not work. This gun is very small, the fps however is not as high as advertised. I recorded the following measurements with a chronograph:
.12-gram average velocity: 186.12 fps
.20-gram average velocity: 143.02 fps
.25-gram average velocity: 111.84 fps
Normally, .12 gram BB's are not used in anything but spring guns, however, I would recommend that you go ahead and use them in this gun, it increases performance dramatically. Personally love this gun, its fun to shoot and to look at. For only $20 this is a great gun to add to your collection. I would not recommend this for airsoft wars because of the short range. Its best for backyard plinking and fun."
