Description
The B5 Systems CAR-15 stock is a faithful recreation of the original polymer buttstock that shipped on early carbines, built for shooters who want a clean, period-correct look on a retro build or simply prefer the stripped-down geometry of a fixed-length stock over a collapsible one. B5 produces it in OD Green, designated CAR-1482, for those building or matching period military-influenced configurations where that finish makes sense aesthetically.
Construction uses modern mil-spec polymer rather than the materials available when the original was designed, which means the dimensions and appearance hold to the classic profile while the underlying material resists cracking and UV degradation better than vintage examples. The butt plate is aggressively knurled to resist slipping against the shoulder under recoil or when transitioning between positions, and the stock includes a fixed sling loop rather than the QD cups or sling mounts common on modern furniture — appropriate for running a standard loop or HK-style sling in a period-correct setup. A cleaning rod channel runs through the stock body, another detail carried over from the original design that gives you a place to store a cleaning rod without adding bulk elsewhere on the rifle.
The stock fits any standard mil-spec diameter receiver extension, so it drops onto most AR-platform carbine and rifle lowers without modification. If you are building a retro carbine and want a stock that matches the look without sourcing aging surplus parts, this is a straightforward solution built to current manufacturing standards.
