Things I liked:

Can't shoot this enough and as accurate as any gun i'e ever used. Most fun you'll have in this price point and likely double it. Has never jammed a single time in over1000 rounds.

Things I would have changed:

nothing

Things I liked:

This is my first purchase of an air rifle and cant say enough good things about it. I was shocked at the overall quality and fact it is built so much like the real AR15,which i own several of and the ease of use is ridiculously easy. The accuracy out of the box is amazing and the overall value is incredible. Ive ordered 3 more similar products in the following weeks since this original purchase but find this particular gun by far,the best bang for the buck and the most accurate rifle Ive ever seen right out of the box. Extremely accurate and reliable as Ive gives through over a thousand rounds and have never had a single jam.

Things I would have changed:

Cant think of anything to change.

What others should know:

If youre on the fence as to which model pellet rifle to purchase,try this model and you cant go wrong.

Things I liked:

The look and feel is very realistic. A little heavy but manageable. Very accurate at 30 meters. I get 4 magazines from a cylinder. I could shoot 5 but the velocity drops off as does accuracy. Not as loud as my Steel Force. I like the Sig red dot sight; very functional and perfect co-witness with open sights.

Things I would have changed:

An extra magazine or belt with the gun would be great and most would pay extra for them. The vertical grip that comes with the gun is uncomfortable for a big hand; not enough room between grip and hand stop. I bought a Barska vertical grip that is perfect.

What others should know:

I read many reviews regarding the velocity of various CO2 guns. But each manufactures description states: MAXIMUM Velocity, not guaranteed velocity. No doubt the manufacturers measure the velocities of their guns under optimum conditions: humidity, temperature with the best performing pellets. I am more concerned with accuracy than less than maximum velocity.

  • Richard from USA asked:

    What does the gun weigh in the standard configuration with the 88-90 gram CO2 cartridge?

    • Randall from USA asked:

      The front of the 2 pack 90 gram CO2 cartridges suggest that an adaptor is needed...doesn't say for what tho....does a Sig MCX require an adaptor for the 90 gram Carts to fit/work in the stock? -John Wick

      • Mark from USA answered:

        No; The 90 gram tank will screw right into the gun.

    • Aaron from USA asked:

      how long can you keep the co2 in the gun

      • Mark from USA answered:

        You can leave the 90 gm tank attached until empty. You would not want to leave for 4 months ,but otherwise it is OK.
