CAA CSR1 1" Picatinny Scope / Accessory Ring

The CSR1 clamps a 1-inch flashlight, laser, or scope tube to any MIL-STD-1913 rail and adds a short Picatinny top strip for stacking a micro-dot or pressure switch. CNC-machined from hard-anodized aluminum, the ring secures with a large thumb-nut for tool-free installation and weighs only 0.25 lb.
