"This is honestly one of the best guns I have ever owned right out of the box it is a great platform and ready to go however the mag isn't quite the best however I ordered an additional 3 mid caps a red dot and a smart charger and this gun was a beast out on the field seeing as I play CQB primarily. The trigger response was great even on a 8.4 which I ran at first because I had changed the stock to a fixed and was rather skeptical of an included 9.6 how ever once I changed back to the included retractable stock and used the battery I found my self extremely pleased with the purchase. Just to show how well this gun preforms I took it out to one of the fields and one of my friends went in to a match while I was still loading so I gave him this m4 when he came out he asked me if it was a krytak! Alas six months later I ran in to my first and only ever problem, I tend to hammer the trigger to hard seeing as I broke the trigger posts.

"Well for me this gun is great. It fires fast and is extremely accurate (and I mean extremely accurate, if you look at the target afterwards all of the bbs are so close together that the bbs are less then about 1 cm apart on full auto from very far away). The iron sights are good but not great in my opinion because I like to see where the bbs go but they are adjustable and can be changed out but they are accurate and you can flip them up and down which is what I do and it works if I have the back one up and the front one down and that works perfectly for me.
Oh and it is also very accurate from far away even though it is cqb.
The only problem I have had is that the magazine it came with is not great, well it's just plain bad, when the gun stops firing and you look at the magazine it has about 30 bbs still in it that the gun won't fire, and I do know that it is the magazine because they are known for being cheap and also because the gun fires all of most other m4 mags
The only other problem I've had is that now the battery that it came with won't charge but I think it is either the battery or the charger but I still have to figure out if it is the gun, the battery, or the charger
Either way I should upgrade to a better charger and battery
I don't think it is the gun though and when the battery is working, it lasts 4ever

"Have had this gun for about two months I believe now and have used it around 7 times at an indoor arena (each visit being 4 hours long with 10-20 minute games and 5-10 minutes in-between games for breaks.) Had loved it for about 5 first days of using it but now not to sure. Have gotten extra mags, foregrip, red dot, flash light mounted on sweet RIS. Was pretty convinced this would be a good gun to build off by how durable and tough the externals are. I have noticed like I have seen in youtube videos at a mid-long range 60-100ft? the bbs drop aggressively. Now my gun is having bigger issues. It hesitates and makes loud noise shooting the first bb of every interaction where I have to shoot. Literally can take up to 2 seconds to shoot after pulling trigger. After that first one is out if I burst fire a few more those seem to come out fine but that first shoot every time is slow, makes very questionable noises and on top of all that. The first few times I used gun (same amount of time and level of use as the visits where I had malfunctioning,) The 8.4 and 9.6 batteries could easily last the whole time I was there with 1 battery, either one. The second two last time I went I went through both 8.4 and 9.6 batteries I bought and the (tester battery) that came with it. In these games I do not get to use full auto ever nor go through more than 1 or 2 mid cap bamf mags per game or half of the high cap it came with. So not a lot of use per game. Last time I went I burnt through all those batteries in like a hour and half. Then rented a battery from the place I went to and that one went fast, which was a fully charged 9.6. So I know it is not my batteries or my charger which some people have recommend to check. It is seeming to get worse, so I have stopped using it and am saving money to have it diagnosed to see If it is worth fixing. Also about to look into if has a manufacturer warranty. Have tried adjusting hopup and the little allen key on bottom of pistol grip to adjust motor height (I believe? late at night, watched few videos and made small adjustments both ways.
