The REC7 combines the familiar ergonomics of the AR style rifle with a revolutionary short stroke gas piston operating system to create a rifle that runs cleaner and more reliably than traditional designs. The onepiece 174 stainless piston interfaces with a strike face that has been machined into the monolithic antitilt bolt carrier. The TB41 DLC coated antitilt full auto bolt carrier is machined from a solid block of 8620 steel with an integrated piston strike face. Both upper and lower receivers are forged from 7075T6 aluminum hardcoat anodized for durability then finished with Cerakote for a perfect color match. The upper receiver and barrel extension feature M4 feed ramps for improved reliability while the lightweight free float handguard features a fulllength M1913 Picatinny top rail with Magpul MLOK accessory mounting slots at the 3 6 and 9 oclock positions. The REC7 piston vents excess gas forward at its patented chromelined fluted gas block resulting in cleaner cooler lowermaintenance operation. It also allows the user to access the piston assembly for maintenance via the front of the rifle without requiring removal of the hand guard or barrel.
