    "This gun is just pure amazing. I got the Echo1 ST6 for my birthday and it’s been performing flawlessly. It shot a clean 17 RPS and a steady 390 FPS out of the box. I used this gun for almost 3 years before the trigger spring snapped.

    I took this as an opportunity to install a high-speed motor, new Krytac High-Perfomance piston, and a new steel trigger spring. With the new parts installed I was getting 23 RPS and 399 FPS. I played with the gun like this for another year before I wanted to make it into a High-Speed SSG build. It’s not completely finished yet but it’s getting a new V3 gearbox, Gate Titan, New Springs, and upgraded HopUp.

    I can only say good about this gun. BUY IT. It will serve you endlessly.


    Cons: RIS and crane stock a little wobbly.
    by Jake M. on 09/08/2017
    "I was a bit skeptical about getting this because people said things about stock wobble and R.I.S wobble and the abs plastic receiver. So I overlooked that and got it anyways and to this day no regrets. I've had it for a day now and I love it! So so accurate best gun under 200

    Rail covers, foregrip,battery
    Loud-I like loud airsoft guns
    Looks great
    Upper/lower reciever is super high quality to worry about it

    Slight slight wobble of crane stock
    R.I.S. moves back a centimeter when you pull back(can hardly even notice it) really don't worry about those two
    by Nicholas P. on 04/14/2017
    "I got this as my starter gun, and I'm very happy with it with one gripe: the weight.

    Excellent Hop-Up
    Great Range
    Good Accuracy
    Comfortable Stock
    Lots of Battery Space
    Good Stock Battery
    Long Battery Wire (so you can change battery w/out collapsing the stock)
    Included Hi-Cap Mag, Foregrip and Rail Covers (all good quality)
    Sling Mount Points
    Working Charging Handle (F-ing COOL!)

    Laser Engravings (some are cool, some just look like an edgy 12-year-old put them there)
    Charging handle doesn't lock back so it's kind of hard to adjust hop-up (but my hop up was great out of the box os idk)

    Front RIS is slightly wobbly rotation wise (especially apparent when using foregrip)
    Safety selector (my field is semi-auto only, and I find I frequently bump the selector out of position)
    HEAVY (this is my major gripe. It feels beefy, sure, but it'll soon tire your arms out)
