KWA KM4 SR10 Full Metal 2GX M4 RIS Airsoft AEG Rifle - MILSIM Edition

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 KM4 SR10 full-sized AEG rifle 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, which lets you run mounted accessories like a tactical stubby vertical forergip. The SR10 stays true to KWA's mantra, and is a top of the line Airsoft weapon that's Engineered To Outperform.

The NEW KM4 SR10 is equipped with 9mm steel ball bearing bushings and a removable metal CQB rear sight, along with a CQB up front sight for accuracy. KWA has installed a lengthy, robust 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, with enough length to even be outfitted with a grenade launcher unit. A clear top sight rail gives you freedom to mount pretty much any optic out on the market.

The SR10, as mentioned before, is a full-size rifle. The extra barrel length over the more compact SR5 and SR7 variants allow for the SR10 to be more powerful and accurate. Because a 5-point retractable rear stock is installed, the SR10 does not sacrifice quick maneuverability. 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.
