Here are 2 polymer cyma shotguns.

The one with the shell rack and picatinny rail works very well and chronos at 290fps with 0.2g bbs. It's over hopping 0.2 so 0.25 is likely the weight to use. This is a mix of a cyma cm.357 shorty and a cyma cm.351. The 357 was originally 2 tone but the blue was removed and resprayed matt black. The receiver on the working one was from the cm.357 and was blue. Everything else on here was originally black. 

The other shotgun racks and shoots fine but it's a bit more random when you shoot it. With 0.2 one bb over hops (like the working one) one bb is flat, and the last bb drops within 10m or so. From memory this is because of a tear in the hop rubber and it will need replacing. Or you could just use this as a parts donor.
