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 one-piece 17-4 stainless piston interfaces with a strike face that has been machined into the monolithic, anti-tilt bolt carrier. The TB-41 DLC coated, anti-tilt, 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 7075-T6 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 full-length M1913 Picatinny top rail with Magpul M-LOK accessory mounting slots at the 3, 6 and 9 o'clock positions. The REC7 piston vents excess gas forward at its patented chrome-lined, fluted gas block, resulting in cleaner, cooler, lower-maintenance 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.
