"I was looking around for a Vietnam-style M16 airsoft gun, and after thorough searching, I came across this gem, Since there doesn't appear to be many reviews for this one, I figured I'd throw in my two cents.

First, let's start off with the externals. The receiver, outer barrel and sight posts are all made of metal, while the stock, grip and handguard are made of high-strength plastic. In other words, this thing is durable, though I'm not sure how it compares to the real steel. I've fallen down and dropped it on the ground, and it still kept going. The Colt and U.S. Government trademarks are excellent touches, too. Nevertheless, there are some drawbacks: there are weird grooves on the outer barrel and "SAFE-SEMI-AUTO" markings on the right side of the receiver. Also, the dust cover stays open. However, none of these are huge issues for me except for the battery; it's impossible to fit a 9.6v NiMH battery without unscrewing the buttplate. Just be careful doing this, because the rear sling swivel can fall out when the screw is removed

Internally, this gun has been solid so far. Somebody on an airsoft forum said that G&P AEGs may need their gears replaced within 30,000 rounds, but I've experienced no gear issues yet. I highly recommend getting a 9.6v NiMH or 7.4v LiPo battery because with one of those, the gun becomes a pellet hose. That doesn't mean it's totally inaccurate, though. The stock barrel and hop-up bucking do the job just fine, but if you really believe that a tightbore barrel or aftermarket bucking will do better, then by all means get one. FPS is just about right, so there's no need to mess with the spring unless your local field has more restrictive limits. What is perhaps the cherry on the sundae is that this gun is compatible with most - if not all - TM-style parts.

To sum up:

-Great firepower
-Great externals
-Blazing ROF
-Good accuracy and range
-Solid gearbox (so far)
-Authentic manufacturer trademarks
-Old school look

-Slight errors in detail
-Hard to put battery in

Overall, this is a great airsoft gun. If you're looking for an old-school M16, then look no further than this one.

"I play airsoft in correct 'Nam era gear and guns and also do Vietnam reenacting. I have brought this rifle to several reenactments/living history displays. Inaccuracies aside, the only most glaring one is the laser etched "Made in Hong Kong" on the left side of the receiver. I cover it with black electrical tape so now its not visible during games, displays and most importantly, in pictures.

The flash suppressor is the correct 'birdcage' type; the ones with full slots. Unfortunately its plastic. Be aware that when replacing it, it is CLOCKWISE threaded like most if not all G&P made guns.

The barrel is also correct skinny 'pencil' barrel instead of the heavier barrel found on M16A2's.

Stock is also the correct length; A2's are slightly longer however the buttpad and trapdoor is plastic. There is a lot of room inside for a large NiMh/NiCd pack and definitely lots of room for LiPo's

The dustcover is non-functional and springs shut. I rather have it that way than have it always open and have the hop dial exposed and visible. its not good for pictures.

The hand guards feel like too plastic-y so I replaced mine with REAL COLT hand guards with heat shields. It fits in perfectly. Put a real COLT or USGI sling and it adds to an overall authentic feel.

Because its devoid of modern attachments, the G&P's weight is only several ounces from the real steel M16A1.

The G&P M16A1 comes with a G&P M120 motor and spins fast and pulls the M120 type spring easily. G&P actually recommends the use of a 7.4 LiPo to ensure reliability. Depending on the C rating (discharge rate) of an 11.1 LiPo, ROF will be in the mid to upper 20's. Powered by a 7.2, rate of fire is a sane 18-19 rounds per second.

With a fresh M120 spring, this will fire over 410 FPS with .20's. Expect the spring to settle to around 390. and because of the long barrel, range on the A1 is amaze-balls, especially using .30's.

I wouldn't change anything on this rifle as most G&P's out of box are above average performers, I would recommend to use a plug in, inline MOSFET when using LiPos and firing mostly in semi to protect the trigger switch.

"I've had this gun for several years, now, and it has served me very well. At the time that I bought it, (and still to this day, I believe) the Colt licenced version is the most historically accurate Vietnam-era M16 on the market. That doesn't mean it's perfect, though (see below). I've used it as my mainstay gun, even when not running a Vietnam loadout. I've used it in bitter cold, and humid, pouring rain (which coincidentally was a Vietnam-themed event).

Some inaccuracies I noticed:
-The end of the barrel is lightly finned. Not sure why. Extra work for them, and inaccurate.
-There are "Safe, Fire, Auto" indicators on both sides of the receiver. On the real M16A1, they were only on the left side.
- "Made in Hong Kong" etched on the side in bright lettering. (I covered it with electrical tape, never tried outright removal)
- The handguard was pretty cheesy. It even bowed outward in the middle. I almost immediately replaced it with a surplus Vietnam handguard, which fits fine and looks fantastic.

And for a bit of balance, some surprising accuracy I wouldn't really expect from airsoft:
-The buttstock is a proper length. The old M16s had a shorter buttstock. I believe it was an inch or two shorter. I also prefer shorter buttocks. But, this also means fitting a large-type 9.6 is very hard.
-The front sight pin is round, not square, as it should be. Would never imagine airsoft having that kind of attention to detail. It boggles my mind how they messed up the fire selection indicators but did something like this correctly.
-While my gun didn't come with it (ordered from redwolf), G&P is the only airsoft manufacturer that I've found that supplies the proper M16A1 birdcage flash hider. For the uninitiated, it's the birdcage were the cutouts go all the way around and are a little further apart than the M4 (which has no cutouts on the bottom to prevent dust kicking up when prone). Remember, G&P's thread are the opposite direction (they are 14mm positive) from most airsoft guns.
