This gun is the M183-A3 version of this shotgun, and I am completely satisfied with it. The gun itself comes fully assembled, and is ready to use right out of the box. It comes with a sling, 2 ladder buckles to attach and adjust the sling, a 100 round speedloader, ~100 bbs, and 4-30 round shells. The sling you have to assemble with the ladder buckles, but once you do that it is very nice. As for velocity, it gets about 390-400 fps constantly with .20's. The stock is very solid, and the iron sights are very accurate. Once you get the hop-up adjusted for the range you shoot at, it is awesome. Good for woodland and field, but a bit powerful for CQB. I contacted Airsoft GI about two shells that I got that constantly jammed, and they are sending me replacements, no charge. Overall, Great gun for the price!
Great FPS (~390-400)
Very real feeling
Speedloader and sling
Shells that I got weren't the best, 2 constantly jammed
