"This gun looks, feels, and shoots great. It definitely sits at least around 380 fps with my 9.6v nimh battery. Speaking of batteries, it’s gonna be hard to find the right one, the recommended battery(2300mha) will definitely not fit, there is a battery on Amazon that’s 9.6 that’s blue and black, I highly recommend those as their very cheap and work great in all my guns. But they barely fit in the handguard, which is where the batteries go. The stock feels really nice, the iron sights are good, and it weighs about 10 pounds with the mag. It feels really nice to use, and it pretty loud, it definitely has a good kick to it, really feels like your hitting pretty hard.

The only issue with this gun is it can be difficult to have that battery in there, but once you get it in you just leave them in. The other issue is with none of my other mags fitting, I thought it came with a hi cap mag, but I got a midcap, which the spring is stuck a little ways down the mags and trying to get it unstuck got my jamming rod also stuck so now it’s pretty screwed up. I do think that those mags are very nice and they previously fit super well in the gun, and would feel pretty well. But I have a a couple lancer magazines and they don’t feed, my evike mags wont fit at all. So definitely buy more CAA mags for this gun. You have to press the mag up against the hopup or push it forward for it to feed properly l, kinda sucks. But when it works it’s great. Semi auto is very reliable, full auto will magdump anything, it actually shot so fast my hi cap couldn’t keep up.
