B5 Modular Picatinny Stock Odg

The B5 Modular Picatinny Stock in OD Green is purpose-built for shooters and operators who demand maximum adjustability and reliability in modern tactical carbines. Developed by B5 Systems—a manufacturer trusted across law enforcement and military units—this modular stock integrates seamlessly into any AR-platform rifle equipped with a Picatinny rail interface. Whether you're running a duty rifle, competition build, or precision setup, this stock provides the ergonomic control and stability needed for consistent shot placement under varied shooting conditions.

The B5 Modular Picatinny Stock leverages a rigid, modular architecture that allows users to customize cheek rest height and accessory mounting without permanent modification to the base unit. The OD Green polymer construction delivers durability while keeping weight minimal at just 1.31 lbs—critical for carbines where every ounce matters during extended operations or dynamic movement. The Picatinny mounting system ensures zero-cant installation and allows mounting of auxiliary gear such as backup optics, cameras, or sighting systems directly to the stock body, freeing up rail space on the receiver.

This stock is ideal for operators running direct-impingement or piston-driven AR-15 and AR-10 platforms that utilize standard receiver extensions (buffer tubes). Tactical professionals and civilian shooters alike benefit from the modular design when transitioning between mission profiles or upgrading accessories without replacing the entire stock assembly. Installation is straightforward—simply slide onto your existing buffer tube and secure via the integrated lock mechanism, making this an efficient upgrade for existing rifle builds. The compact 6.75-inch collapsed profile and extended reach ensure compatibility across shooter body sizes and equipment configurations.
