Material: Aluminum alloy Slot: 9 picatinny rail width: 20 mm Bottom dovetail rail width: 11 mm rail length: 100 mm Dovetail rail length: 75 mm Guide type: W/P rail Can be used to convert 11 mm to 20 mm Model number: P Key benefits Expands compatibility by converting 11 mm dovetail to 20 mm Picatinny rails, enabling use of 20 mm accessories on platforms with 11 mm interfaces. Durable aluminum alloy construction provides reliable performance while keeping weight manageable. Tworail design with a 100 mm rail and 75 mm dovetail rail offers stable support and versatile mounting length. 9slot rail allows flexible accessory positioning and secure mounting options. Simple, direct conversion solution without requiring multiple adapters or complex setups. Specifications at a glance Material: Aluminum alloy Slot count: 9 rail: 20 mm width, 100 mm length Bottom rail: 11 mm width, 75 mm length Guide type: W/P rail Conversion: 11 mm to 20 mm Model: P Use scenarios Scenario 1: You have a platform with an 11 mm dovetail base and need to mount a 20 mm Picatinny accessory such as a sight, optic mount, or accessory rail. Install this guide to enable a secure 20 mm interface. Scenario 2: During field setup, you want to reuse existing 20 mm compatible accessories on equipment that uses 11 mm rails. Use the guide to bridge the two rail systems without swapping components. Scenario 3: A modular build requires occasional 11 mm to 20 mm conversions across multiple modules. The P guide provides a compact, consistent solution for quick swaps and reliable alignment. Notes Model P. Designed as a W/P rail guide to convert 11 mm to 20 mm rail interfaces while maintaining alignment across 100 mm rail and 75 mm dovetail sections.
