"My friend owns this gun and I owned the ICS O.A. M4A1 RIS and he lets me use it whenever I want, and stock this gun is one of the best I have used. It's accurate, has a respectable ROF, shoots just hard enough for the competitions I go to, and is one of the most durrable airsoft guns I have used. Externally, it's very pleasing to the eye, all metal, dense plastic on the grip, motor grip, and stock, and the rest is all metal. Detailed enough that it looks good, but doesn't cut into cost for those looks, so you save that little bit of money on that. Put an M203 and the heat shield for it on this and you have one sexy beast.
Internally.... wow. That's all I can say if asked about it, this has to be one of the easiest, if not THE easiest gun I have worked on including an ICS O.A. M4A1, CA G36, JG G36, Dboy M4A1, JG M14, and a G&G Soc16. All of those guns have a standard gearbox, and are a complete PITA to work on, where as the Olympic Arms have a unique, but absolutely awesome 2-piece setup that makes any sort of work so much easier. The upper reciever houses the Tappet plate, piston, cylinder, spring, etc, while the lower reciever holds the gears, selector switch, and trigger mech, along with the motor of course. This alone makes this gun worth the money, but only if you plan to work on it, if you're just into small skirmishes, and nothing too terribly serious, or if you're not too sure if airsoft is for you, or if you want to save money, then I wouldn't recommend this gun. However, if you know airsoft is your kind of sport, you love the game, and have some cash to dump into a nice, reliable gun, then I would always point towards the Olympic Arms M4/M16 series guns; these aren't just a purchase, but an investment in performance and excelence.
"great gun it shoots fast and hard the magazine is good but it is a little lose not a problem just buy another high cap or like i did i bought some good mid caps and they work the best great feed and light and not to mention very quiet and you can keep shooting without turning the wheel but you have less ammo. anyways that's your decision. all in all a great gun the price is a little competitive but like they say you get what you pay for. all metal and a full metal 2 piece gear box. the gear box is great to work on if you get a simple jam just take it out nice nice and your good to go. the nice thing about this weapon is the huge battery compartment so you can hold a massive battery for long play and ROF. the stock and foregrip are plastic, abs plastic to be specific that means it a high grade. dont be turned away because of the plastic parts they will hold up for a while. another long life maintenance saving thing is the push button spring release this you should press after play or before storage you press the button and it releases the pressure on the spring which results in longer spring and gearbox life. a great feature from ics. the sighs are fully adjustable also it has the removable carrying handle for a scope or laser anything will do. the flash hider is removable so you can put a barrel extender or silencer on it. this is a great gun you will be satisfied great for experienced players and intermediates not so good for beginners however but its a awesome gun must have for your armory.
