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.

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."

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
