Product DescriptionDesigned for pairing red dots with magnifiers, night vision, or thermal devices, the Bravo Company A/T Optic Riser 525-11 provides a stable, elevated platform while keeping snag hazards low. Measuring approximately 4.5 inches long with 11 recoil slots (12 lugs), it raises the optical centerline by 0.525 inches-bringing typical lower 1/3 optics to about 2.16 inches and absolute co-witness optics to about 1.93 inches. The A/T (Angled Torque) interface uses a patented clamp to deliver strong, reliable lock-up on Mil-Std 1913 Picatinny rails. Machined from aircraft aluminum alloy and hard coat anodized per Mil-A-8625F with a nitride-treated steel clamp, this riser is built for durability and repeatable zero.Product HighlightsElevates optic centerline by 0.525 inches for improved awareness and PPE/NVG compatibility11-slot riser with multiple integral recoil lugs for secure, repeatable mountingPatented Angled Torque clamp provides stronger, more reliable lock-upLow-profile, snag-resistant design maximizes usable rail spaceAircraft aluminum construction with hard coat anodizing; nitride-treated steel clampSpecsProduct Type: Picatinny optic riserLength: approximately 4.5 inHeight Increase: 0.525 inRecoil Slots / Lugs: 11 slots / 12 lugsCenterline Heights: ~2.16 in (with typical lower 1/3 optics); ~1.93 in (with absolute co-witness optics)Mount Type: Mil-Std 1913 Picatinny railMaterial: Aircraft aluminum alloy; hard coat anodized per Mil-A-8625FClamp: Steel alloy, nitride treatedFinish: Matte blackRecommended Torque: 40 in-lbsCountry of Manufacture: USAUPC: 812526023889Manufacturer Part Number: BCM-OR-AT-525-11Brand Name: Bravo CompanyPatent: US Patent D973,826; other patents pendingDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
