This low-profile red dot sight mount base is a dedicated Picatinny rail adapter compatible with 407K, 507K series red dot sights and other optics with identical footprint designs.

We are a professional precision metal parts manufacturer focusing on CNC Milling and custom machining service. This mount is manufactured via a full production workflow: extruded aluminum blank forming first, then precise multi-axis CNC Milling to reach ±0.02mm tight dimensional tolerance, followed by 120# abrasive sandblasting, and finished with hard black anodization for outstanding scratch resistance and anti-corrosion performance. Its overall dimension measures 40.8mm × 29mm × 11.7mm.

Every retail package is equipped with a full hardware kit: 2pcs M4 T10 countersunk torx screws for each length (6mm, 8mm, 10mm, 12mm), plus one L-shaped T10 torx wrench for convenient installation without extra tools. The low-profile design keeps your red dot close to the rail, reducing recoil shift and maintaining compact equipment layout.

• Picatinny rail mounting for HOLOSUN 407K, 507 series red dot sights
• Replacement and upgrade of original red dot mounting brackets
• Tactical optic modification, gunsmithing and DIY optic build projects
• Low-profile compact red dot installation to minimize recoil deviation
• Matching assembly for all red dot optics with same 407K/507 footprint
• Bulk custom optic accessory production for tactical gear brands

As a trusted manufacturer of CNC machined tactical components, we provide comprehensive CNC Milling service, custom service and OEM manufacturing solutions:

• Custom design & machining based on your technical drawings, physical samples or supplied aluminum blanks
• Customize mount overall dimensions, rail width, hole positions and footprint cutouts
• Diversified custom surface finishes: different anodized colors, fine/coarse sandblast textures
• Custom laser engraving: private brand logos, model marks, serial numbers
• Custom hardware matching: adjust screw lengths, thread standards and drive types
• Custom retail packaging, private labeling, small batch & mass order support
• Extended CNC Milling service for all kinds of aluminum brackets, optic mounts and fastener assemblies

• Professional CNC Milling processing with ±0.02mm ultra-tight tolerance: eliminates loose wobble, gap and misalignment issues that generic cheap mounts have, locks red dot firmly under recoil
• 120# sandblast + hard black anodized surface: resists scratches, sweat and environmental rust, avoids paint peeling after frequent disassembly
• Complete matched hardware kit pre-packed: contains all needed T10 torx screws and matching wrench, saves your time sourcing separate installation tools
• Low-profile streamlined structure: shortens the distance between red dot and Picatinny rail, cuts recoil-induced zero shift to guarantee consistent accuracy
• Universal compatible footprint: compatible with 407K and identical-design red dots, one mount covers multiple optic models
• Professional manufacturer with stable production capacity: supply flexible CNC Milling service, custom service and OEM orders to solve your personalized optic bracket customization demands

• We execute full-process strict quality inspection for all CNC Milling optic mounts:
• Raw aluminum alloy material incoming inspection: verify metal composition, hardness and flatness
• Real-time dimensional testing during CNC Milling production to strictly control tolerance range
• Surface treatment batch inspection: check sandblast uniformity and anodized coating thickness, reject blister or discolored products
• 100% visual appearance screening: remove parts with burrs, scratches and machining defects
• Physical fit test: assemble with matching 407K 507K red dots and Picatinny rails to confirm seamless installation
• Recoil simulation stability test to verify locking performance
• Complete batch traceability records for every CNC Milling production run
