Things I liked: Really over all great gun.its really realistic. I have to be careful where i live. Because it looks so real.feels like a real gun in your hands.

Things I would have changed: Its pretty accurate at 100ft its grouping about the size of a quarter. But ever 5 to 6 shots you get a stray thats about 2in out.could just be the pellets.

Things I liked: It has the weight and feel of an actual AR type platform. Feels good to my hands. Sights are fairly easy to adjust once I figured out how the strange looking tool that came with it works. It really is a 30 round rotary belt magazine. I carefully went over everything. Most of the AR parts are just for show and do not function but they do look like they would work. The hammer is fairly light and smooth so I won't complain about that. It's nice that it has a tool storage in the pistol grip. I was a bit worried I might lose that tool. The barrel shroud is metal and heavy so I'll need to get used to that. No real grumbles about it.

Things I would have changed: The rotary belt you put pellets in I found a bit confusing. I had to be very careful to keep it oriented properly so I didn't load the pellets in the wrong way which could be a problem. I got to remember silver front white back.

What others should know: Really nicely built gun. I have not been able to shoot it yet since 88 gram co2 is a hard thing to find where I live and I did not buy the pcp bottle kit.

  • Gavun from USA asked:

    Do hollow points work in it?

    • Tyler from USA:

      As long as they are not super long, yes. I've used H&N crow magnums with no issues

  • Lawrence from USA asked:

    does the Suppressor work?

    • Tyler from USA:

      Yes, it does dampen the noise a bit

  • mrmrogden from USA asked:

    In what way is this new?
