Each PRS Sling shell holder gives quick access to two rifle rounds when the hunt turns hot - the pair provides four extra rounds total, positioned for fast reloads without slowing movement. Built from mil-grade, durable materials, each holder locks into the MOLLE slots on PRS and Hands-Free rifle slings for a secure, low-profile carry that stays put during vigorous activity. Intended as a modular add-on, the holders can be used singly or together depending on mission needs and install quickly into the sling's MOLLE slots. Rugged construction and positive retention make them a reliable choice for hunters and backcountry shooters who want immediate access to a small, lightweight ammunition reserve. Sold as a pair.
