"I have seen some negative reviews on this gun, but I think those people have just had some bad luck, mine has been great. I had used a lot of aegs and I was tired of all the problems that could occur and the poor performance. I tried out a gas gun and it did NOT disappoint! The rifle has great distance with amazing accuracy! The mag holds 20 bbs, and I have gotten 20 kills in a row before.
Perhaps you have seen an enemy hiding in dense underbrush or tall grass and you tried to shoot them with your aeg, but the bbs just bounced off the vegetation. Not with this gun, the gas propels the bbs cutting straight through thick underbrush and keeping power at far distances, and the bbs don't start to drop after 50 feet.
The kick on this gun when it shoots is awesome! It feels great and actually moves the gun, but it is not intense enough to throw off accuracy! The sound it makes from the blow back is awesome! It may not be that practical to shoot it in full auto, but it definately turns some heads when you do! The gun also breaks down almost just like the real m16. For realism and performance, this gun can't be beat!
I run a Vietnam load out, and this gun is perfect for it! I put a lot of time and money into my authentic load out, so I needed a rifle that was just as cool, not any of those crappy Aegs. Also, the gas is held in each mag, as with all gas rifles, so it makes life a bit easier not having to worry about charging your battery, just pump some gas into the mag.

So I have been praising the gun, so now I have to list some cons. This gun needs a lot of maintanence, but no different than any other GBB rifle, you need to clean and lube it after every day of playing. This isn't exactly a con, since you should do this with all GBB, but it is kind of a pain. Every few months the barrel might get a little loose, and need to be tightened, but WE has included a special tool to tighten the barrel with.
The mags only hold 20 bbs, which is t exactly a con, because it is realistic, and great for mil-slim! The mags may not hold as much ammo as an aeg, but the rifle makes up for it with its performance! I have held my own against aegs slinging their torrents off bbs out there, meanwhile I make my shots count! Plus extra mags are $25, which is a good deal for a gas mag! Another con is that gas guns do not really work in the cold, of course aegs don't function at their best in the winter either, but at least aegs work. But so long as it is at least in the high 50s and your gun is well lubed you shouldn't have any problems. The gun feels a bit light, which isn't really a con, because it weighs about the same as the real m16 used in the 60s. Plus the gun has a solid feel to it, other than the hand guard, but the hand guard is supposed to feel that way.
You will want some extra mags if you are going to do matches with this gun. I have 5 mags total, plus my sidearm, and so long as I'm not wasteful, that is usually enough. This gun is compatible with the 30 round mags, but the short 20 round mags are much better. My whole team uses WE open bolt GBB, and they will all tell you that my short mags are better. The long ones seem to have more problems, and the baseplate on the bottoms of the mags come loose, but these short mags are very sturdy and they have a much better feel to them!
People say to only use green gas in your gun, but I have been using propane in my. So long as you keep it well lubed you should be fine, it hasn't given me any trouble.

Overall this is probably the best gun I have ever used. I give it 5 stars. If you are looking for a realistic, high performance Vietnam era weapon, then this is hat you want! I am never going back to aegs... Except for my m60, they don't make GBB LMGs, sadly.

"This is a nice gun. Has a nice weight to it and the recoil kick is something else. I would highly suggest taking it apart and cleaning off all the excess grease and oil, then give it a nice lube job. I have found no reason to file or mod any parts in order to make it work. Maybe some folks have had to do it, but not me. I do not like the "semper fi" engraving on it. Not that I have anything against the Marines, I think it looks toy like without the more realistic trades. I would highly suggest getting the NPAS and installing it. I did, and I can actually use this rifle at the local fields. The NPAS is really easy to install.

"Will definitely need modifications. I must admit when people said this gun should be for experienced airsofters they were right. You will literally have to file, scrape, and trim the parts in your rifle for it to function properly, and every magazine that you buy as well. Green Gas Mags Only!!! The co2 ones Do Not work. And the Ra-Tech bolt carrier will not fix the bolt catch either, you have to mod your rifle. It's a shame that you pay good money for something that doesn't work, but I guess if you have the time, money, and patience it will work out.
