The M4 RIS rifle is the latest offering from the APEX line of affordable and high quality AEGs. This carbine features a durable polymer frame, metal receiver, 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. The M4 RIS rifle has an extensive integrated metal Keymod rail on the top of the rifle and quad side railed handguard, making it available for customization options such as optic sights or tactical lights. Use the A-frame style frontsight and adjustable flip-up rear sight to quickly and accurately zero in your targets. This rifle features APEX’s high quality Version 2 metal Gearbox and 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.The 380 FPS (0.20g BB) ensures you can easily use this rifle in long range engagements, while still being legal in most CQB and indoor matches!A flat trigger design is installed into this model which allows the airsoft gun to have an improved trigger pull shot after shot. The tri-prong flash hider has an aggressive design different from a standard birdcage design and can be removed for the addition of a QD mock suppressor. 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! APEX thought of everything and made this rifle both unique and very functional.
