Our Take: KWA has always been manufacturing the industry's most prevalent AEGs engineered to function smoothly and reliably right out of the box. The KM4 SR10 Generation 3 model takes that level a step further. This full-sized AEG rifle features the all new 2.5 system and their kinetic feedback for a realistic recoil punch in every trigger pull. Externally, its rugged full metal construction (full metal receiver, barrel, internals), a high-quality enhanced gearbox and ultra high-torque motor set up, and a Mil-Spec-1913 full metal free floating rail system, lets you run mounted accessories like a tactical stubby vertical foregrip.

KWA's KM4 SR10 is equipped with 9mm steel ball bearing bushings and a quick spring change system. This airsoft gun also 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 is a full-size airsoft rifle, and 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. In addition, KWA has perfected an AEG to similarly replicate the AR-15 model. The comparison allows limitless customization to cater with the airsoft user's interest. So customize away and feel the realistic kickback from one of KWA's finest!

Features:
- Free Float MIL-SPEC-1913 Rail Adapter System.
- One-piece full metal alloy upper and lower receivers.
- Full metal Version 2 Gearbox built with 9mm bearings.
- Full metal outer barrel buffer tube for durability.
- Electric 30/120rd magazine cut-off prevents AEG to automatically stop firing.
- Switch life extender prevents contact burnout.
- Standard upper 20mm monolithic rail for optic attachments.
- Quick change spring system.
- Upgraded high torque motor and high speed gear set.
- Measured inner barrel size of 425mm in length.

Battery Charger Recommendation: Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery (overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly). Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.

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
