The B5 Systems Precision Stock is an FDE, adjustable AR-platform stock that combines the stability of a fixed stock with the versatility of a standard carbine stock (brand part no. CPS-1305). B5 Systems molds it from durable polymer and fits it with internal tensioners so it won’t rattle on a Mil-Spec carbine-length buffer tube, then adds an elevation-adjustable cheek rest and an extending rubber buttpad to dial in a consistent cheek weld. Dual QD sling sockets, dual fixed sling loops, and bottom-mounted M-Lok slots round out a stock built for serious range and duty use. It’s a genuine upgrade for shooters who want fixed-stock consistency without giving up carbine-length adjustability.
