Bought this gun about 5 months ago. I've skirmished with it 4 times. I am a huge fan of the M1 Carbine so I had to have it. The gun has a great finish and is pretty close to my real steel gun. Mine shoots around 370 fps which is perfect for my field. Accuracy is decent, but not the best. Biggest con is the mag size - 15 rounds just like the real steel one. I have used it in games against normal AEGs - it is more challenging but I've gotten kills with it. If you like to spray BBs this is not your rifle. If you prefer a stealthy approach and can wait for your shots, this is an awesome gun.
I get 5-6 mags out of one co2 cartridge. Mags are expensive and you're probably going to need 2 extra (45 rounds total). The mags can be a little tricky to reload, but you can use a speed loader to help. I have gone into battle and reloaded a mag mid game.
Make sure this gun fits your play style before buying! I'm giving it 4 out of 5 because of its cost.
Super light weight. You can run and move very easily with it.
Blow back is cool.
Realistic - 15 rounds per mag! But this could be a con.
Expensive, mags are expensive also.
Can be challenging to skirmish.
Hop up and accuracy could be better.
Haven't found good pouches for the mags yet.
