Samson Scout Style Optic Rail for Ruger PC Carbine Black. Our PC Scout Rail replaces the front and rear sights on your PC Carbine and allows you to attach BUIS Scopes Red Dot Sights or Night Vision devices. (Shown in photo in red for contrast. Standard models are black.) Due to the PC Carbines unique takedown feature mounting the optic to the barrel assembly maintains zero and increases repeatability that receiver-mounted options simply cant match. It's the ultimate PC Carbine accessory.
