B5 Systems SOPMOD Precision Stock Medium Length – AR-15/M4

The B5 Systems Collapsible Precision Stock (Medium Length) delivers enhanced cheek weld and improved recoil control for AR-15 platform rifles. Its SOPMOD-style design features a wider, extended cheek rest that promotes consistent head placement and faster target acquisition, particularly valuable for optic-mounted setups. The stock's rubberized buttpad reduces felt recoil and prevents slippage during rapid fire or awkward shooting positions.

Constructed from reinforced polymer with a matte black finish, this mil-spec compatible stock fits standard carbine receiver extension tubes and installs via a single locking lever. Internal waterproof battery storage compartments provide convenient space for CR123 or AA batteries. The medium length profile balances compactness with a secure shoulder mount, making it suitable for both close-quarters work and precision shooting applications.
