This is my first gun and I've fallen in love with it. As have my teammates. This gun is a blast. I opened the box and I felt as giddy as a kid again. The gun is HUGE!!! And it just looks AWESOME. Out of the box it chroned at 338 FPS, and came with the standard 8.4v battery. The FPS is that with and no upgrades to anything. I took it down to a pond by my house and tried it out. At first, it seemed like horrid range with .20 Premium BBs. I fired about 1000 rounds and then it jammed. Once I opened up the gun and fixed the problem and my Hop Up unit, I fell in love with it. Range and accuracy had increased to a rather impressive level, spread, and firing rate. The spread of the BBs was perfect and even though it's not the most accurate weapon around, you'll be sure to hit someone with at LEAST one BB with the amount you'll be dishing out.
I recommend buying a 9.8v or a 10.8v battery however, as mine died after about an hour of heavy use (it comes with an 8.4v standard batter and charger). Also, you may want to invest some money in a sling, as this weapon does become tiresome to run around with after some time without a sling. I personally am also going to get another ammo box because this thing pours through BBs. At least it does for how I play.
All in all, this gun is good at what it was built for. A support weapon that is a blast to play with: It's very real looking, looks great, and very intimidating to your enemies while being a welcome sight for your team.
4.5/5 for the M249 MKII by A&K
5/5 for the men and women of Airsoft GI. I bought a Smartcharger from them, however, they were out of stock. Not only did the man (Tyler) at customer service recommend a better one for around the same price, but he "comped" the difference between the two chargers.
-High Rate of Fire
-Ammo box has continuous feed and runs off of AA batteries
-Includes a heavy duty carrying case (which is easily as heavy as the gun)
-Comes with some trades (at least my did)
-Comes with battery, even though it does not say so in the description.
-Full metal and very sturdy
-High BB use (what do you expect with a support weapon?).
-Heavy (again, expected, but can be dealt with and not as bad as I thought)
-Not the most accurate gun in the world (duh)
-Ammo box on it's automatic feed can be rather loud and annoying (however it has a silent setting so it's not really a con)
-Carrying case is as heavy as the gun. Can be a problem for smaller players when just carrying it around in the carrying case from point A to point B.
