KWA KM4 RIS Full Metal Railed M4 Airsoft AEG Rifle w/ 2GX Gearbox

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 KM4 RIS is one of the most popular KWA M4-series AEG rifles of all time, designed to DOMINATE the Airsoft arena indoors and out.

The KM4 RIS is equipped with 9mm steel ball bearing bushings and a full metal removable rear iron sight. KWA has installed a full length, metal laser-engraved integrated rail system for quick upgrade potential, allowing you freedom to customize your weapon with add-ons such as lasers, tactical flashlights, or even compact grenade launcher units. A top optics rail also lets you run optics like a Trilogy Tactical 1x32 Red/Green Dot CombatOptix Scope. The KM4 RIS is a full size AR-chassis carbine rifle that has the versatility of a carbine and the versatility that comes with the integrated metal rail system.

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.
