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 ALL-NEW NS2-equipped H&K-Licensed MP7 blowback fully automatic sub-machine gun [SMG] is at once brutal and yet breathtaking at the same time.  The undisputed king of RPM, this blowback SMG can fire over 15-16 rounds PER SECOND, totaling over 950 rounds per minute!  Solid, realistic, and quality built, the KWA MP7 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 KWA MP7 features both rails (located on the top, left, and right of the hand guard area) AND a folding/retractable forward grip, features that are almost always mutually exclusive (you either get one or the other) on compact SMGs.  The MP7 is quality constructed from a fiber reinforced polymer composite with a steel barrel, allowing for a lightweight and highly maneuverable SMG that is built as tough as it looks.  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 MP7 features a functional/realistic charging handle and a functional bolt release.  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 MP7, 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.

To answer your question

"Yes it consists of a counter clockwise 12mm to 14mm threading. It is a pain in the butt to take off though. It was put on with something called loctite, and you have to take a part of the gun apart to access the threading. go on google and type in a how to remove it."

Great feel, looks great!

"Overall a great gun. Really happy with this one for the most part. This is as close as you can get to the real deal. You'd swear you were holding the genuine artifact when you pick it up. Everything on this gun performs as it should. It's durable and functional. I haven't chronoed it yet, but my guess is that the numbers are pretty close. The RPS is fairly high and they small mags empty quickly if you're not careful... although that's what you should expect out of these GBB guns. My only complaint is that this thing is painfully inaccurate. I guess it's ok for CQB, but the fact that I can't hit a beer can from 20 feet away is pretty annoying. I have a $30 spring gun I use for plinking and it out shoots this gun any day of the week. I guess if you are in a CQB environment and you go full auto at a relatively close range you'll hit just about anything. So far though, testing a variety of ammo hasn't done much to help the situation but I'll keep trying. I was able to find an adapter to get standard silencers on this puppy, but it does add a tiny bit of length to the gun and it makes it a little less attractive than if it had been fitted with a factory suppressor. Other than that, take this out in the yard and have a blast. You'll swear you were firing a real weapon. It probably sounds close to what a real one would sound like with a silencer. Great gun."

Best in Class Customer Service

Same Day Will Call Pickup

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
