This optic adapter blank is formed via aluminum extrusion molds first, then processed by full numerical CNC milling for ultra-precise edge shaping, threaded hole drilling and positioning pin seat machining. All critical mounting structures maintain a strict ±0.02mm machining tolerance to eliminate assembly gaps and optic wobble after installation.

After CNC cutting work, every single base receives uniform 120# sand blasting to clear all machining tool marks, then undergoes hard black anodizing surface treatment to deliver scratch resistance, anti-oxidation performance and smooth matte appearance.

This mount perfectly matches mainstream optic footprints: RMR, SRO, 407C, 507C and 508T, securely fixing compact red dot optics onto universal 20mm Picatinny rails. Each retail package comes with a complete matching hardware set: M4 T10 Torx screws in 6mm, 8mm, 10mm, 12mm lengths (2 pieces per size), plus one L-shaped T10 Torx wrench for straightforward assembly.

• Accessory base to attach compact red dot optics onto devices fitted with standard Picatinny accessory rails
• Supporting hardware for recreational range activities and outdoor sports equipment setups
• Aftermarket optic replacement spare parts for global sporting goods retail brands
• Custom CNC-machined optic adapter plates for international distributors, online retailers and private label brand owners
• Equipment modification hardware for hobbyist outdoor gear assembly and personal optic setup upgrades

As a reliable CNC machining manufacturer, we deliver one-stop custom service and OEM/ODM precision machining for all optic mounting hardware, covering every stage of product customization:

• Sample & Drawing Customization: Accept customer physical samples or CAD design files (STEP, IGES, DWG) to duplicate or redesign RMR optic mount bases and optic adapter plates.
• Material Customization: Adjust aluminum alloy grades, or switch raw materials to stainless steel, brass upon client requests.
• Structural Customization: Modify overall product dimensions, hole layouts, positioning pin designs and machining tolerance values to fit exclusive custom optic footprint standards.
• Surface Finish Customization: Adjust sandblast grit sizes, swap anodizing color options, add laser engraved private brand logos, product model codes or custom graphic markings.
• Hardware & Packaging Customization: Alter screw lengths, tool types, and print client brand logos and information on retail packaging boxes.
• Large Batch OEM Production: Offer flexible minimum order quantities to accommodate small trial batches for new private brands, alongside volume-based unit price discounts for large OEM bulk orders.

• CNC precision machining with ±0.02mm tight tolerance creates seamless fits between optic unit, mount base and accessory rail, preventing optic movement during long-term regular use.
• Complete matched set of M4 Torx screws and dedicated L-shaped wrench included inside every package, end users do not need to source separate installation tools or fasteners.
• 120# sand blasting paired with hard black anodizing creates a durable protective layer, resisting surface scratches, oxidation and outdoor environmental exposure without quick finish fading.
• Direct factory manufacturer offering full custom service and OEM machining, no middle trading markup, helping brand buyers cut total procurement costs for large bulk orders.

• Raw Material Incoming Inspection: All aluminum extrusion blanks pass alloy composition testing and dimension checks before entering the CNC machining production line.
• Mid-Production In-Process QC: Coordinate Measuring Machine (CMM) random sampling inspection to verify critical hole tolerances and outer contour dimensions during CNC milling runs.
• Surface Finishing Batch Inspection: Random batch sampling to test sandblast surface uniformity, anodizing film thickness and salt-spray anti-oxidation performance.
• Physical Compatibility Fit Test: Every production batch undergoes hands-on fitting trials with all supported optic footprints and standard Picatinny rails to guarantee smooth assembly.
• Finished Goods Full Visual Inspection: 100% manual visual screening to remove finished units with machining burrs, surface scratches or cosmetic defects; full hardware quantity matching verification before product packaging.
• Complete Production Traceability: Full production run logs and inspection records preserved for all custom service and OEM orders, supporting complete after-sales quality tracking.

Q1: Can I place OEM orders for RMR optic mount bases engraved with my private brand logo?

A: Yes, our custom service supports laser marking custom brand logos and model codes onto the aluminum mount surface, and custom printed retail packaging boxes are available for bulk OEM orders.

Q2: What design files should I provide to start custom CNC machining of optic mounts?

A: You can send physical product samples, CAD files including STEP, IGES and DWG formats, or detailed dimension specification sheets; our in-house engineering team will confirm all production parameters for your custom order.

Q3: Will this optic base fit all standard 20mm Picatinny accessory rails?

A: Fully compatible, the bottom clamping groove is CNC machined strictly to universal 20mm Picatinny rail specifications, working with nearly all devices equipped with standard Picatinny rails.

Q4: What is the minimum order quantity for custom OEM machining orders?

A: We provide flexible MOQ options as part of our custom service; small trial batches are welcome for emerging private brands, and larger bulk OEM orders qualify for reduced unit pricing.

Q5: Can I request custom anodizing colors other than the standard matte black finish?

A: Absolutely, we can produce anodizing finishes in dark tan, flat grey and other custom tones, plus adjust sandblast grit numbers fully per your custom requirements.
