"I bought this 556 about 3 years ago. Great FPS out of the box (about 385 with .20 gram bbs), incredible range, very cool-looking gun, and realistic weight. Gearbox is excellent, never had a gearing problem over 3 years of airsoft. Everything is metal that should be, and the polymer parts (stock, handgaurd, and handgrip just behind the trigger) are just as durable. Just went to an OP and this gun was dominant over AK's, M4's, Saws, and G36's. Great gun for lone wolfing/sniping. M4 mags are ideal for this gun as you can get them in metal, unlike the polymer mags that come with it. I bought 500rd 1,000rd high cap M4 mags and they work great. Buy a 9.6v stick battery to increase rate of fire. I've used a one point bungee sling which makes the gun easy to carry despite its weight. Basically an awesome gun that will last forever, look way cooler than everyone else' gun, allow you to get long range kills, and inflict enough pain to make cheaters call their hits."
