The M4 10” Keymod AEG is the latest offering from Lancer Tacticals’ line of affordable and high quality AEGs. This carbine features a durable nylon reinforced polymer frame, metal barrel assembly, full metal gearbox and ergonomically designed polymer pistol grip. The ergonomic motor grip ensures perfect grip in any battle conditions and greatly reduces player fatigue by improving overall maneuverability. The adjustable crane style stock with attached sling mount opens up many options for CQB and long range skirmishes. This M4 Carbine has an extensive 10 inch integrated Keymod on the top of the rifle and quad-rails on the handguard, making it available for customization options such as optic sights or tactical lights. For a lighter more slim profile, this rifle comes with 2 removable 6-rib rail segments, and a single removeable 10-rib rail section. Use the flip-up front and rear sight to quickly and accurately zero in your targets. The M4 RIS Carbine features Lancer Tacticals’ 2nd Generation Version 2 Gearboxes with metal parts, which can be easily upgraded or modified to user preference. These gearboxes come out swinging with an upgraded motor with 8mm ball bearings to ensure the gears spin more efficiently with less friction and less need for repairs. Lancer Tactical made sure this rifle comes skirmish ready by including a vertical grip, 9.6v Nunchuck style battery and wall charger with every package. The included wall charger has an indicator light to let players know when their battery is fully charged, and will automatically shut off when full which greatly prolongs battery life. The 400 FPS (0.20g BB) makes this rifle the perfect choice for long range battles. The integrated Quick Spring Change System gives you the option to easily adjust the rifle velocity by adding different springs. Low resistance wiring is used throughout this whole rifle, to greatly increase smooth electrical flow from the battery. Use the adjustable rotary style hop-up to account for range and wind conditions, making sure no enemy is safe! Lancer Tactical thought of everything and made this rifle both unique and very functional.
