Things I liked: The concept the looks the feel

Things I would have changed: Feeding issues leaks magazine getting stuck price for its crapyness should be lot lower

What others should know: Had this for about 2 years not worth the money in any way shape or form had to send it back two times going to a third time and a said it is junk so much and too much is going on inside the rifle itself does not function the way that it's supposed way to much jaming used hard pellets like they digested tryed others didn't matter not worth the money doesn't shoot like it should leaks then they don't even send me a replacement just keep trying to repair the same f****** gun don't waste your money on this if I could all honesty I would give it zero Stars my background is a military infantry Plus Gunsmithing paintballing hunting all that so I'm not new to the game and not one that writes much of any reviews unless really good or poss poor like this one

  • Jacob from USA asked:

    What type of grain would you recommend for this specifc firearm?

    • John from USA asked:

      Just wondering why the release date for this airgun keeps getting pushed back. Hope it's not problems with SIG. Pretty excited to see how it performs. Wish they could have worked the folding stock into it, but I understand the 88g C02 has to fit there.

      • Micheal from USA:

        according to what I heard its just bugs like games that first come out they have bugs they want to make sure its perfect for us and it wont hurt us when we use it they also want to make sure it has the promised fps and muzzle velocity and also want to make sure that your not getting something that will break down in a few days at the price who would want it to

    • johnson from USA asked:

      Does the PCP model will coming later? I saw the Airgun show report that they have Co2 model and PCP model. If the PCP model is going to come later,does anybody know when is coming? And what is the details,something like the max speed,the energy,the pressure for the cylinder...

      • ted from USA:

        Just get the 13c.i. HPA and adapter and now you have a PCP version. I did and I love it, works flawlessly and you get a little more fps and more shots per charge.

      • Micheal from USA:

        I haven't heard indication that they will have a pcp modle although I feel your envy I would love a pcp model also
