Our Promise:  KWA AEGs are renowned for their world-class performance and exceptional build quality.  With an exceptional 45-day factory warranty and LIFETIME tech support offered directly through KWA, we feel most qualified to be YOUR premier KWA dealer.  In addition, you are guaranteed to pay the absolute LOWEST price on the market for your new KWA AEG rifle, backed in writing by our industry-leading 125% Lowest Price Guarantee.

Our take:  KWA is engaged in manufacturing the industry's most prevalent "LiPO ready" AEGs that are engineered to function smoothly with Lithium Polymer batteries right out of the box.  With rugged full metal construction (full metal receiver, barrel, internals) and a solid enhanced 2nd generation gearbox, the KWA KM16BR "M16A4 Battle Rifle" is a top of the line Airsoft weapon designed to dominate any game it's thrown into.

The KM16 is a full length AEG equipped with 9mm steel ball bearing bushings and a full metal removable carry handle.  KWA has installed a full M16 rear stock to maximize battery storage space.  The M16 Battle Rifle's ultra-long, full metal tight bore barrel enables the rifle to be one of the most, if not the most accurate and powerful rifles in its class.  KWA's line of AEGs is priced at a premium for a reason:  they offer the hottest rate of fire "out-of-the-box" performance on the market and have internals that will last considerably longer than any of the competition.

KWA USA stands behind their product and offers a 45-day warranty and lifetime tech support on all KM4-series AEGs.

Battery and charger are NOT included.  Airsoft Megastore recommends 9.6v NiMH mini-type batteries with standard NiMH Smart Chargers for this rifle.

5 KWA Full Metal KM16BR Battle Rifle M16 Airsoft AEG w/ 2GX Gearbox *****
KWA 2gx M-16

"The gun is a beast! I had been using the KWA 2gx M4A1 for a year, and I loved it, but since I play "field" I wanted an aeg with an edge over the other players. Without a doubt this gun is the best gun I've ever used straight out of the box.I opted to use an intellect 10.8 nimh battery, which although slower than a lipo makes this gun spit rounds at an incredible rate. I used it today, and got 10! kills in just the first team death match round I played.All of those hits were well past 50 feet. I was not hit that round, still had two respawns when the game ended!. This gun had people cowering, I was hitting people a good 30-40 feet further out than my previous aeg,and more than one opponent cried out after being hit. Pros-509mm inner barrel,130 spring,2gx/20+rps/not sure the fps but at least 400?,it went THROUGH a pizza box at 50 feet. Cons- Some players who need to attach lights, foregrips,peq's,juice boxes,and asthma inhalers to their "rails" might not like this gun, as it has only a top rail under the carry-handle.To me, this is actually a "pro", since it might keep people from purchasing this gun. When I play airsoft, ALL I care about is hitting my target, and rails to me are a waste.Maybe for real guns, in a tactical environment I would want them,but not for hosing down juveniles on a saturday morning.Let the other guy waste his money. KWA sr 12's w/the same inner barrel length are almost $100 more in price, for basically the same gun, but with rails and an adjustable stock. So for me this gun has no "cons"!"

SR12 is the same model internally

"I have the SR12, but since that has been discontinued by KWA and since this gun is the exact same internally I figured I would review here. This gun has it all: reliability, accuracy, rate of fire and feet per second. It shoots ~400 with a .2, and the RPM is around 19rps with a 9.6v. I personally don't use LIPO, but it is LIPO ready. I use the full stock which has massive battery space to store a large 9.6 that lasts me the whole day."

"this gun is amazing, it is full metal and indestructable, no matter what u do to this gun it keeps firing and the fire rate when it is on full auto is faster than any other gun that you would face on any airsoft battlefield i had an airsoft war the other day and my friends took my gun to make sure that i was not cheating because the fire rate was so high i reccommend getting a 9.6v battery and an extra 350rd kwa mag Pros: -very high FPS -excellent range and accuracy -full metal -full scale replica -adjustable hop up -very high rate of fire -this gun never breaks -adjustable sights -removable carrying handle -large stock that holds a large battery -comfterable when holding for a long time -it could be an sniper with its high accuracy and long barrel if u put a scope on it -its worth the money -magizine has a tight fit and doesnt wobble Cons: None overall this is the best gun on the market and it is very high quality, KWA did an amazing job at building this M16 "

Good Gun Buy It

"This gun is probly the best m16 thats less then $500 on the market. The gun itself has already lasted through 10 airsoft battles of mine and still works like the first day i got it!!! The sling is not the best but it was free so I cant complain. Not getting a battery with it was a bumer but if ur going to plan to buy the 11.1v battery well its not that bad then. just make sure when buying the battery from this website you dont get the long stick-like one. you need more mags if you plan on doing hard core airsoft wars. all in all this gun diserves a 5 star overal rating. "

KWA m16a4

"Wow, thats the first thing i thought when i shot it. Its a loud firing gun that with .25 shoots very fast. Accuracy out of the box is great and overall best out of the box gun ive seen. Not sure who the smart one was that put .2 in it and wrote about it but the guns papers said not to shoot them, Great Job! "

Best Gun I Ever Got

"All around a deadly gun, great FPS,accuracy,and ROF is sweet with 11.1 lipo battery. very well pleased with the construction of the gun, good weight and the plastic parts are very durable and will last a long time. the only thing I would want more is R.I.S on the hand guard. but other than that i am very excited about it. it gets the job done and then some. great support weapon, and u might want to get the 500rd mags because this bad boy with put down some heavy fire, and just remember if you are going to put optics on it you need to get the raiser mount that goes on top of the carry handle. But it all boils down to, GET THIS GUN!!! you will not regret it."

best m16 on the market

"wow! when i first picked up this gun, i was suprized on how bnalenced this gun was. it felt great. absolutley no wobble. theres a TON of battery space. i can fit a 5000mah 9.6v. i modded it with a g16 ergo grip, a silencer, and a dboy grenade launcher. it DESTROYS on the field. Pros: lightweigt FPS chronoes at 431.4 advereage with .20s! extremely modable accuracy ROF 880-910 with a 9.6v very fun to shoot Cons the accuracy is ok but not that great as i expected. i plan to get a tightbore soon"

"Great gun. better then Olympic Arms even. the fps i don't think is quite what 420. doesn't really hurt that much. but it shoots super far and accurately. it's practicably solid metal. Very impressed with it. defiantly use the LiPo battery. and get some extra mags. after the warranty is up, 45 days, i plan to open it up and see whats inside and maybe upgrade it. oh ya, and it come with a 350 rnd mag. defiantly worth that money."

Best Airsoft Gun I Have Ever Owned

"This gun is truly excellent! I cannot describe how pleased I am with this product. This rate of fire and power with a intellect 9.6v battery blows me away. if you are looking for a professional grade airsoft gun I would highly recommend KWA. Pros: EXTREMELY well built (no wobble whatsoever) Almost everything on this gun is metal Very powerful (390-410 fps) Very high rate of fire Removable carry handle Cons: Absolutely nothing! I would recommend .25 Golden Ball bbs and a 9.6v battery with this gun. Overall a fantastic gun. KWA, I am your biggest fan!"

Good Price, Good Gun

"The KWA m16br is an excellent gun; the picture here does not do it justice, it is a matte black full metal/polymer stock. the selector switch is crisp and nice to use. The box the gun comes in said that it recommends .25 or heavier, as I didn't have those I used .36 sniper rounds. They are effective for brush but drop quickly even with full hop-up. The spring will settle in a bit lowering fps by around 20 making 380-400fps. I haven't used it for a long range battle with my friends yet, but I suspect it will do well; it can reach to 100ft fairly easily with no hop-up with .20's; .25 with full hop will no doubt reach 180-200ft no modifications. It's a great gun overall"

good gun

"For experienced players.very good gun,however it doesn't come with a battery and charger and you have to use. 25 bbs which slows down its power.around 400 fps.can go about 300 feet straight but about 200 feet accurate. Get a 9.6 battery.also recommend a 2 point sling 1 point isn't good for this gun.over great quality gun but would recommend just getting something more reasonable."

"plugged in 9.6 1600 battery and cycled the selector from safe to semi, functioned fine, semi to auto, functioned fine, and back into safe and stored over night. The next day when cycling from safe to semi, the rifle will behave as if it is still in select safe mode. When cycling all the way to auto (functions) and back to semi it will function on semi, but not from safe to semi, only auto to semi. Contacted KWA Customer service, they were helpful, sending it back, hopefully when it comes back it functions as should."

The store is amazing. I have found there items that I could not find in other stores which makes it the best. I have made questions and inquires about products and the customer service has responded super fast with accurate answers. All my products have arrived in excellent conditions in spite of other stores. My last product came late because it was rescheduled but that was UPS fault I think. I would like to thank Matthew for his exceptional customer service. Whenever you need help, please try to contact him. My advice, buy in Airsoft Megastore, they have coupons and the widest variety of airsoft products. RandyLoy, USA
I ordered a gun sling a couple weeks ago. Unfortunately, one of the clips broke. After a few email correspondings with a customer service representative named Jun (my emails did not show a last name), AMS sent me a replacement sling for free. I did not even have to send my clip back. AMS is a terrific store and I plan on doing more business with them. They were polite, efficient, and just a pleasure to work with. I would recommend Airsoft Megastore to anyone. mskanwischer, USA
Airsoft Megastore is The Best Airsoft Website Out There (I Think) and i Will Always Be Loyal to AMS and Order Almost All of my Gear From Them. The Customer Service is Also Amazing, Jun my Customer Service Representative Has Helped Me With Anything i Needed Help With, Especially My Order Problem (Had 2 Magazines Missing from Order) and Jun Helped Me With The Problem, and Now The Mags Have Been Shipped To Me. Thank You So Much AMS and Jun. Ethan1214, Saskatchewan, Canada
I love that Airsoft Megastore has videos of most any information you will need to learn and care for your products. I purchased an AEG for my son and in short order, unfortunately, it began grinding after brief use. I emailed for warranty repair with symptoms and with 24 hours (22 to be exact) I received an email explaining possible causes with a video like for tuning the gun. I had the gun working again within 15 minutes, avoiding returning the gun and the mess associated with returns\repairs. Excellence on Sean's part to help out a first time customer of theirs. Highly recommend. bucfanjeff, USA
Everything worked great, shipping was super fast. I am very pleased and won't hesitate to order through airsoft megastore again. rob_riley, USA
