Things I liked: the automatic burst , the ability to reload fast, the rail mounts the double co2 options there should be more co2 guns with the ability to have 2 co2 tanks to boost power and stuff. it looks like the real gun of this version.

Things I would have changed: i would have change the damn bb loading door cause it slides open when you shake the gun to reload i have to find a way to fix that.

What others should know: i bought this before the elite force umarex came out , if you could id suggest getting that one but if not this one is good to for a automatic burst.

Things I liked: Accuracy is very good. Easily converted to a remote tank. Shoots fast high rate per minute Top and Bottom Rails is a big plus

Things I would have changed: noise suppressor its a very loud gun, stock option, a lot more power would be nice

What others should know: This is the most dependable full auto in its class. Once you add the external tank. You can burn through 300-1000 BB's very quickly.

  • gary from USA asked:

    Where can I get folding stock for it?

    • Dan the Man from USA:

      Pyramyd does not offer one.

  • Michael from USA asked:

    This thing is the most fun you can have without a class III, but mine has developed a leak in the seal where the magazine/cartridge storage goes into the pistol. IS there a replacement part and/or a fix available?

    • Robert from USA:

      Pyramid air sells spare co2 mags. If that doesn't fix the issue, replacement O rings in the gun sometimes fix leak issues.

    • Dan the Man from USA:

      You would have to ask Umarex at 479-646-4210 ext 7.

  • Sebastian from USA asked:

    Where's the bulk adapter? I've searched the recommended accessories and can't seem to find it.
