The Reptilia RECCE SR-15/M4/AR-15 Carbine Stock delivers a lightweight, versatile solution for AR-pattern rifles, offering a constant cheek weld, ambidextrous QD sling attachment points, and a rubber buttpad within a modular design that can accommodate either a standard AR15 carbine buffer system or an A5/SR25 carbine buffer system by swapping the receiver extension and forward portion of the stock. Weighing just 12.0 ounces including the proprietary AR15 carbine-length receiver extension, this stock provides a reliable balance of strength and reduced weight for the entire spectrum of AR-pattern rifles from compact builds to precision configurations. The RECCE Stock is designed to support fluid, repeatable cheek placement and rapid sling transitions, while the adjustable length of pull of 10.80 to 14.20 inches ensures a personalized fit for diverse shooting stances and gear setups. Built with durability in mind, it integrates seamlessly with the SR-15/M4/AR-15 platform, delivering a cohesive, ergonomic feel that enhances control, accuracy, and end-user comfort across demanding field, range, and training scenarios.
