Our take:  The WE Full Metal M4A1 Gas Blowback Rifle (GBBR) features the latest WE Tech open bolt design and is more resistant to cold weather than most other gas airsoft guns.  Shooting at around 420 FPS (w/ 0.20g BBs) and featuring a full metal bolt, this M4A1 gives players arguably the most realistic recoil on the airsoft market.  The WE M4A1 features a removable carry handle that exposes the upper receiver rail, which is perfect for any standard rail mounting optic.  This is the perfect gas blowback M4 rifle for any player looking for both high performance and realism.

Features:
- WE open bolt design w/ higher tolerance for cold weather
- Hard kick recoil
- Adjustable LE style stock w/ sling mount
- Front sling mount
- Full-length inner barrel for extended accuracy

5 WE Airsoft Full Metal M4A1 Open Bolt GBBR Gas Blowback Rifle - BLACK *****
Very nice gun, with unlimited possibilities

"*THIS IS A FIRST IMPRESSIONS REVIEW* First impressions for me are very high on this rifle. The first thing I did upon this rifle's arrival is a basic field strip, basically just removing the bolt carrier group and checking internals as well as functions. This gun is very easy to take apart and all the functions on it, including a forward assist, are there and fully functional. This gun is very easy to run if you are familiar with the real AR rifles. LUBRICATION: This gun came very dry as far as lube goes, and I feel that this is why some people rate this gun low out of the box. I lubed the bolt carrier and internals sparingly with silicone oil (all you really need is a bit on the contact points on the bolt carrier) and the gun worked much smoother. MAGAZINE: The magazine that came with the gun worked flawlessly, I have not seen any of the issues that some people have had; for example, the tab for the bolt catch not working and the mag leaking gas. Everything seems to be fine, I haven't had any misfeeds, or failure to lock the bolt back after the last shot. And as far as gas efficiency goes, I can do two mags on one fill before I start significantly losing gas pressure. SHOOTING/CONSISTENCY: The speed of the bbs seems to be quite consistent, I don't have a chronograph and I'm not going to try to guess, but the speed is pretty decent and consistent for a gas rifle. The accuracy seems to be getting better the more I shoot this gun, there is a pretty decent break-in period. I am probably around 200 rounds in and my groups are about 4in at 20 yards with the stock iron sights, which is pretty good for an airsoft gun. The gun also has a very nice kick, which has that kind of bouncy feel that the real AR/M4 rifles have; however, this gun obviously has much less horizontal recoil. It is comparable to a .22LR rifle, with a bit more "jumpy" feel. LOOK/FEEL/MATERIALS: This gun looks a lot like and weighs about the same as an M4A1 rifle, maybe slightly more because of the heavy magazine. It feels really good to hold, and is very comfortable if you are used to AR type rifles. Basic but good buttstock, and a tight ring holding the handuard in place makes shooting this gun easy even with stock parts. The gun is made of what appears to be a cheap cast metal, but it is more than sufficient for airsoft use. UPGRADES: If you want to upgrade/customize this gun, the possibilities are pretty much endless as with all decent M4 type rifles. this gun is manufactured with Military-specific size parts, so it slightly limits what you can get, but there is still quite a lot out there for decent prices. And of course, all external parts can be interchanged with mil-spec parts from real rifles and the gun actually comes with a real double heat shield handguard, front sight, carry handle and buffer tube and buttstock, all of which are also used on real rifles. CONCLUSION: Sorry about the long review, but I really wanted to cover pretty much anything I could think of. Overall, I have never been happier with the purchase of any airsoft gun, and I would recommend this gun to anyone, beginner or expert. If you want realism, this is about as close as you will get with an airsoft gun. All external functions are exactly the same as a real rifle. Once you break it in, this gun can be very accurate and consistent. and it is compatible with a multitude of aftermarket parts so you can make this gun exactly what you want it to be. So, if you are on the edge about this rifle, I would suggest you go for it. If you take care of the rifle, it will almost certainly perform to your expectations. And I have looked everywhere, and Airsoft Megastore has this gun for the absolute lowest price PERIOD. Thanks AMS, pleasure doing business with you once again."

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
