"I finally got to use this gun for an 8-hour event. I used a Titan lithium-ion 3000mAh numchuck battery in an after-market PTS buttstock w/battery compartment. This gun ran all day until hour 6, where the battery died from shooting about 1500 rounds. The gun is a well-built live weight replica and shot well once the hop-up was adjusted. The conditions were rainy and wet, with no failures. Buy this gun and you won't be disappointed with the quality and reliability. I WOULD SUGGEST, THOUGH, getting the Titan lithium ion 6000mAh numchuck battery and PTS stock w/ large battery compartment for longer play times.

"It works well right out the box with a good 11.1. Its really accurate and feels pretty close to a GBBR. I had to do some upgrades to my TM NGRS but this is pretty solid with OEM parts. The mags are good, and I like the ability to switch between milsim and midcap mags on the fly, with just the flick of a switch on the bottom of the magazine itself. The stock wiring in the stock and the stock itself are horrible. I put a milspec b5 stock on that had more room and shortened the cables so everything can fit comfortably. Range is outstanding, and it hits hard with 0.32's. Trigger response is fairly good, nothing amazing.

"Great build quality. Good range and the recoil on these are a lot of fun. The PTS furniture just puts this KWA ERG over the top. Great alternative for those wanting to add a bit more realism to their gameplay but don't want to hassle with owing a GBBR. Very sturdy externals and the performance isn't amazing but will easily hop .30s out to 200ft and would make a great 2nd or 3rd rifle for weekend skirmishes just because of how fun it is to get that extra recoil from your shots. 9/10 from me. KWAs are still top 5 in my opinion just on quality and realism alone. The only con is when fully dressed up with an optic, lights, and batteries and bbs the rifle is on the heavier side. I wouldn't recommend for younger players because a 10-12lb AEG does get heavy if you are planning on running it for longer games or any milsim OPs. Still a great replica in my opinion. Defintely wortn the $400 price tag.

"Overall excellent gun, fires about 400-410 FPS. Metal body and blow-back feels like a real M4. Only downside of the gun, if it counts as a downside, is hop-up takes sometime to get ready and fire accurate shots. You need to spend one magazine of 100 BBs in order to warm it up.

"Great M4 rifle. I�ve put about 5000 rounds through this rifle with absolutely no malfunctions. I use this rifle primarily for training purposes for my USPSA competitions because the look and feel and weight of this M4 is exactly identical to an actual M4. ( actually, it�s a pound or so lighter ) I Purchased this M4 because I needed a rifle that was completely reliable, durable and long-lasting. This KWA M4 completely fills that need. I highly recommend this rifle.

"I have always been a huge fan of the Tokyo Marui recoil shock system, (next gen recoil shock), having owned a SCAR L, 2 m4 sopmods, and an mk18 made from a sopmod, i was absolutely obsessed with these. the major problem with those rifles is that, despite the incredible range and almost perfect hop (literally like having an rhopped Prometheus TBB, prowin hop, prommy purple bucking, rhoppped) by the TM gnome running around inside the chamber, the guns were shooting extremely low (like 255fps with .25s)

well, my local shop told me i would enjoy this gun, as much as i hated the looks i trust this man, he knows his stuff and he knows my habits as a consumer. Well, having the ability to shoot just as accurately, at 380 fps, and being able to buy 120rd mid caps (without buying PTS emags at 35 a pop) this gun actually even KICKS harder than a TM NGRS.

I'm extremely impressed, and im glad i can finally order the uppers!!!!

"bought it locally from a field i go to and i have to say, its one of my new favorites , it feels like a gbb but with the benefits of a battery
