Wilson Combat WC-15 billet lower has zero slop in the takedown pin lugs when mated to a quality upper. Machining is precise across all surfaces. Black anodize is dark and consistent. Wilson's typical attention to detail shows in every aspect.
Wilson Combat WC-15 billet lower has consistent anodize that matches my Wilson billet upper exactly. Zero play at the takedown pin lugs. Machining is precise. Premium lower that completes a Wilson Combat build cleanly.
