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.  The ALL NEW KM4 SR7 DEVGRU features rugged full metal construction (full metal receiver, barrel, internals), a high-quality enhanced 2nd generation gearbox and ultra high-torque motor set up, and a Mil-Spec-1913 full metal free floating rail system.  The SR7 stays true to KWA's mantra, and is a top of the line Airsoft weapon that's Engineered To Outperform.

The KM4 SR7 is equipped with 9mm steel ball bearing bushings and a removable rear metal CQB sight, along with a flip up front sight for accuracy.  KWA has installed a metal free floating MIL-SPEC-1913 Picatinny RAS [Rail Adapter System]; this laser-engraved RAS allows for quick upgrade potential, giving you freedom to customize your weapon with add-ons such as lasers, tactical flashlights, or even compact grenade launcher units.  A clear top sight rail gives you freedom to mount pretty much any optic out on the market.

The SR7 combines the functionality of a full size M4 with the compact versatility of a CQB weapon for ultra-quick maneuverability without making compromises to power or accuracy.  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 a 9.6v nunchuck battery with a standard NiMH Smart Charger for use in this rifle.

5 KWA KM4 SR7 DEVGRU Full Metal M4 CQB RIS AEG Rifle - MILSIM Edition *****
Pro gun for Pro players

"KWA. 'Nuf said. Seriously though, if you aren't worried about flashyness or whether people like the looks of your weapon but rather are more concerned with how your CQC rifle out performs standard custom field guns straight out of the box, the KWA KM4 series gun is the only gun you should ever consider buying. Whether it's this beautiful SR7 or an SR5 or their new sportline CQR MOD 1 or 0, you will never go wrong with buying a KWA. Known for reliability and performance, the SR7 DEVGRU is simply another member to a long line of tradition paired with modern technologies bringing you to the realization that with KWA, you get what you pay for. The differences between the SR7 and the DMR platform SR10 lay in both size of externals and cylinder venting. This gun is designed specifically for CQB; to be a CQB gun it needs to have an energy output with .20 gm bbs of less than 1.145 Joules (about 345 fps). So KWA put a rear high vent cylinder in this gun to reduce power but maintain consistency. The RIS on the SR7 is a 7" free float picatinny metal rail that reduces overall length and weight while still maximizing versatility, mobility and personilzation. Performance is what we asked for; KWA answered with the KM4 SR7 DEVGRU."

Great gun, don't buy it here though.

"The price is great... before you add the 360 round magazine (that comes standard at other sites) and the battery (also standard). After adding those 2 very necessary items, the price goes up higher than any other retailer I've seen. $390? C'mon. You could buy the KWA SR10 and get 400 fps instead of 330 and get a longer barrel and more RIS space for the same amount of money from another site. This gun should go for $340 tops, INCLUDING the 360 rd magazine. Get your act together AMS."

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
Everything worked great, shipping was super fast. I am very pleased and won't hesitate to order through airsoft megastore again. rob_riley, USA
