"I got this gun used but fixed and upgraded for Christmas and I have to say that its really great and I love it. Mine has upgraded internals, extended inner barrel with a suppressor for much longer range. As the description says it does shoot 395 w/ .20s, with the 11.1v Lipo battery I use .25s (don't use .20 w/ lipo , you'll regret it its much less accurate) and it shoots 388-392 and it has great range and accuracy to it and I do not regret getting this gun and its good for close-mid range and some long range to but nothing like a sniper lol.
Full Metal(could be a con for some people)
If you'd like to check out the gun with some spray paint I have on it check my instagram @cheitocheito
"Owned for about a year now, and it still performs excellent. I loved the unique design. 400 fps out of the box, yes, with decent range even for a short barrel. Full Metal. Installed a Mad Bull 363mm 6.01 inner barrel, Matrix 11.1 Lipo and it shot 445 FPS, 23 ROF. Also, you can hide the Matrix Lipo comfortably in the hand guard (I hate peq boxes). The rail system accommodates a site, laser and flashlight, so I don't know what that other guy was talking about. I STILL haven't had to break down the upper gearbox, (maybe I'm lucky), but it comes with the ICS upgraded upper unit, and it's doing fine. What I like about their split gearboxes in general is that it gives you the flexibility to instantly switch upper gearboxes due to field regulations. For instance, for CQB fields, I remove the stock, 363mm barrel and silencer, and drop in the stock inner barrel and an m100 spring upper, which drops the fps to spec and transforms the CXP into what we call the "space pistol." As an aside, note that you will have a proprietary hop-up unit, AR lever, buffer tube, and bevel/pinion gear mesh that will take some careful shimming if you wish to change.
All this said. why this gun doesn't cost $300+, I haven't a clue.
"Very happy with the performance of this impressive gun. Shoots over 400 fps out of the box and has the beefed up upper gearbox. Amazing long distance accuracy for only a 200mm barrel. The peq box will only handle a small Lipo so I swapped in a bigger one. The stock looks funky but is really comfortable. This is a pretty heavy little gun, especially when you add the battery up front. Don't plan on running optics because of the unique upper rail design. One of my favorite things by far is the fact you can have a unique looking gun in the sea of m4's at the field. Would definitely buy again!
