Our Promise:  KWA GBBs are renowned for their world-class performance, their revolutionary NS2 gas delivery system, and meticulous 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 Gas Blowback Pistol, backed in writing by our industry-leading 125% Lowest Price Guarantee.

Our take:  KWA's NS2-equipped M11A1 gas blowback fully automatic sub-machine gun [SMG] is at once brutal and yet breathtaking at the same time.  With an uncanny ability to achieve a high rate of fire, this blowback SMG can fire over 1,000 rounds per minute!  Solid, realistic, and quality built, the M11A1 is a step towards the future of Airsoft from KWA, as it allows for reliability, power, ultra high rate of fire, and realism without even slightly compromising ANY of the aforementioned characteristics.

The M11A1 is quality constructed from a polymer composite casing/frame, with metallic internals and a threaded barrel for maximum performance.  This allows for the M11A1 to be lightweight and highly maneuverable, yet durable at the same time.  The rear folding stock has been designed to easily and comfortably fold out of the way when it's time to reduce the size of the weapon in tight-wound CQC scenarios.

Firing wise, the M11A1 features a functional/realistic cocking handle and a functional bolt release (with realistic bolt movements).  Much like a real firearm, the bolt locks in the "OPEN" position when you are out of ammo, in which case you can keep it in the open position, reload the gun with a full mag, then depress the bolt release to continue firing (it literally does not get any more realistic than this).

The M11A1 is equipped with the new NS2 gas system, fires crisply and consistently on either semi or full-automatic mode.  The blowback and realistic sound that comes as a result of the SMG's crisp firing is indescribable, as you must shoot one yourself to TRULY enjoy the juxtaposition of recoil and realistic firing noise with the smoothness that only a NS2-equipped GBB can deliver.

The NS2 Advantage:  KWA's proprietary/patented NS2 internal gas delivery system, implemented in this pistol, uses an advanced light weight composite gas piston with a two-stage internal expansion chamber to deliver gas more effectively to the chamber and BB, when compared to traditional gas blowback systems.  This significant improvement in efficiency and power sharply increases the cycle rate of any NS2-equipped KWA gas pistol for the most crisp, clean blowback action on the market, unrivaled by any other GBB.

5 KWA M11A1 Airsoft Gas Blowback SMG Submachine Gun *****
i bought this gun it is amazing

"i just got this gun in the mail a few hours ago i have fired about 5 clips and i have nothing to complain about it is a very accurate gun provided you don't hold the gun the way they do in the movies however they dont tell you to do one thing NEVER pull the bolt back with the safety on it jamed up my gun thankfully i got it unjamed but it was stressful the rate of fire is awesome and firing on full auto makes it look like you are making clouds and emptys the clip in just barely over 2 seconds the only bad thing about this gun is that i might have to buy more ammo before the day is over "

Great gun!

"I no longer have this gun but back when I was heavy into airsoft about 11 years ago I had a KWA M11A1 and I loved it. I was on an airsoft team of about 30 or so people and we would play almost every weekend. this was just one of the guns I had and I would take it out often when in CQB games, it never gave me problems and was decently accurate for its size. The FPS was good and the rate of fire was like no other, I would recomend this gun with confidence."

"all people wondering about this gun, its a great gun, my friend has it and can basically be the best player on the team against some people with masada's and the infamous A&K m60. I personally own the kwa m9 ptp, usp match, kz75 and kmp9, and i HIGHLY recommend this brand for gas guns. i soon will buy the kwa g36c and write a review about it, but BUY KWA ALL THE TIME!!! :D "

Responding to the Few below me.

"Ok for everybody wondering, this gun has a standard threaded barrel. It is made of metal, including the orange tip, and is 14mm counter-clockwise threaded barrel. So basically it fits almost every barrel extension that is 14mm since I have almost never seen a clockwise threaded barrel. I suggest a madbull extension gi since thats were i bought mine from."

"This is a very good gun for the price. The Pros and cons are listed Pros: Accurate High rate of fire Light Stock folds in for tight CQB No gas leakage Barrel adaptable to silencers and tracers Cons: Not a problem with the gun, just that magazines are priced high. Recommendations: A propane adapter makes for less expensive gas because green gas is just propane with a fancy label A speed loader makes it easy to load the mag. By hand it can be difficult (especially if you have big thumbs) and with the speed loader it takes about 5 seconds Extra mags are convenient because this gun will go through one in about 2 seconds.

great lightweight gun

"Overall, it has a great weight, and just feels awesome in pretty much every way possible. It isn't really made for long distance shots, so if that's what you're going for you may want to pass to the next weapon in your list, but if you need a lightweight weapon for quick draws or getting from point A to B fast, this is for you. Personally, im most interested because i like to incorporate a bit of free running into my combat scenarios and this is the best design for that purpose i've come across to date. also, in reference to dax_7's question below, you could probably hold it pretty well in a universal pistol holster due to its small size and similar structure, but if you really want something more specialized, i'd try redwolfairsoft dot com. i'm fairly certain they have a holster specific to the mac11 to begin with, but if not, they have an mp7 thigh holster that's also said to work well with m10-m11 models also."

4 KWA M11A1 Airsoft Gas Blowback SMG Submachine Gun *****

"i recieved this gun a few days before one of my many airsofting parties... i kept it a secret to get the element of surprise. i must say it is an amazing gun in firing rate , but accuracy is ok, and the gun burns through ammo sooo quick. also, sometimes when you pull the bolt back to fire and pull the trigger, nothing happens, EVEN if you fill it fully. i must say this things dominates at close range, but only as a sidearm, dont go rushing in expecting to be the hero of your team. this is a good gun to add to my armory overall, and it will be great once i get a spare mag."

Terrible plz read

"This is a copy of emails to KWA as Megastore wanted nothing to do with their own sale: I purchased the M11A1 SMG for my son's birthday on Sept 5 from Airsoft Megastore. We opened it this past Saturday for play on Sunday. After 1-2 clips of use it "clicked" and stopped working. When we ejected the clip; 2 parts fell out and the gas leaked from the gun. Needless to say this pretty much ruined the "airsoft war" part of his birthday for him. I would also like to say that upon opening the box, I noticed that the top of the box seemed too large for the bottom. Also,I noticed that the slide and relief pin seemed to have been worn a bit. Concerned that we may have been shipped a "refurb" or older model, I looked on YouTube for "unpackaging a M11A1." It seems that packaging has been changed and that is a concern of mine. I have to say, that I am very disappointed at this point and the return policy is( at best) tedious... This was a brand new purchase and to "jump through" all these hoops and pay for return is a horrible experience. If you thing Megastore backs the products they sell.. they do not.... They require me pay shiipping, 10% restocking as well as put up with bad attitude for a produce from their website, all the while, directing me to KWA. Can't "wash your hands" off bad business practices...."

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
