Made by the legendary Airsoft manufacturer ICS, the CXP-APE Keymod Airsoft Rifle is the new and improved ACR style AEG. Externally, this full metal AEG sports a CNC machined Keymod rail system for mounting airsoft accessories such as lights, lasers, grips, bipods and more. The modular Keymod design allows the shooter to have their accessories where they need them, with a slick and lightweight surface on unused portions. Three 5-Slot rail sections are also included by ICS to start mounting accessories right away. The ACR improves upon standard M4 platforms by adding features such as an ambidexterous mag release, charging handle, and fire selectors making it perfect for left and right handed shooters. Additionally, a folding, extendable SF1 style stock with sling mounts and an adjustable cheek riser can make the rifle fold down to a mere 32.5" long for transport or CQB engagements. Internally, the ICS Version 2 Gearbox has a unique split design seperating the spring and piston assembly from the gears, making it extremely easy to maintain and modify. The gearbox comes with a M120 spring preinstalled for an overall 390-400 FPS with 0.20g BBs. The electric blowback system also adds movement to the faux bolt assembly for added realism.
