Reptilia AUS 35mm Optic Mount - 1.54" Height - FDE Anodized

Single-Piece Billet Construction - 39mm Bore Height - Made in USA Introducing the Reptilia AUS Mount for 35mm diameter magnified optics. Driven by the request of an end user group, the AUS Mounts are the culmination of a 2-year development program. The AUS Mount attaches to any M1913 Picatinny rail via Reptilia's anti-snag spring-loaded nitrided steel clamp and custom bolt mounting system which can be tightened with either a 5/32 hex or flat blade driver to sit flush with the body of the mount for a low-profile, streamlined design. Machined from a single piece of billet 7075-T6 aluminum and finished with MIL-STD Type III, Class 2, hard anodize coating in Flat Dark Earth. Features 35mm diameter bore, 39mm (1.54 inch) bore height, and accommodates up to 77mm objective lenses with clearance over flat-top Picatinny rails. Weight 168 grams. Like all Reptilia products, the AUS Mount is 100% made in the USA and carries a full lifetime warranty against manufacturer defects.

End User Driven Development

The AUS Mount was driven by the request of an end user group, ensuring the design addresses real-world operational requirements. This 2-year development program incorporated feedback from tactical shooters and precision rifle users to create a mount that meets demanding field conditions and performance standards.

35mm Diameter Bore

The 35mm diameter bore accommodates the growing selection of magnified optics utilizing the 35mm tube standard. This diameter proves increasingly popular for LPVOs (Low Power Variable Optics), prism scopes, and other magnified optics designed for tactical and precision applications. The 35mm bore provides secure mounting for these modern optic configurations.

1.54" (39mm) Bore Height

The 39mm (1.54 inch) bore height positions magnified optics at an elevated height ideal for passive aiming with night vision devices and shooters preferring upright head position. This height proves optimal for helmet-mounted NVGs while maintaining comfortable shooting stance and proper chin weld. The elevated position also accommodates modern shooting techniques and helmet/ear pro configurations.

Single-Piece Billet Construction

Machined from a single piece of billet 7075-T6 aluminum, the AUS Mount eliminates joints, fasteners, or separate ring caps that could introduce flex or shift under recoil. The monolithic construction provides maximum rigidity for maintaining zero during hard use. Single-piece design also reduces potential failure points and simplifies installation.

Billet 7075-T6 Aluminum

The 7075-T6 aluminum material provides exceptional strength-to-weight ratio. This aerospace-grade aluminum alloy offers superior tensile strength compared to 6061 aluminum while maintaining lightweight characteristics. The billet construction ensures consistent material properties throughout with no casting defects, porosity, or weak points.

MIL-STD Type III, Class 2 Hard Anodized Finish

The MIL-STD Type III, Class 2 hard anodize coating in Flat Dark Earth provides superior wear resistance and corrosion protection. Type III anodizing creates an exceptionally hard, durable surface that withstands environmental exposure, weapon cleaning solvents, and tactical use. The FDE finish offers professional appearance with reduced reflectivity and tactical discretion.

Anti-Snag Spring-Loaded Clamp

The anti-snag spring-loaded nitrided steel clamp simplifies installation while providing secure rail attachment. The spring-loaded design automatically applies proper tension during mounting, ensuring consistent clamping force. The nitrided steel treatment creates an exceptionally hard, wear-resistant surface that withstands repeated installation and removal without damaging rail surfaces.

Flush Mounting Bolt System

The custom bolt mounting system sits flush with the body of the mount, creating a low-profile, streamlined design that eliminates snagging hazards. The flush configuration avoids protruding hardware that could catch on gear, clothing, or vegetation during tactical operations or field use.

Dual Tool Compatibility

The mounting bolt can be tightened with either a 5/32 hex driver or flat blade screwdriver, providing flexibility in tool selection. This dual compatibility ensures users can install or adjust the mount with commonly available tools, proving valuable in field conditions where specialized tools may not be readily accessible.

77mm Objective Clearance

The AUS Mount accommodates optics with up to 77mm objective lenses with clearance over flat-top Picatinny rails. This generous clearance accommodates large-objective LPVOs and magnified optics while maintaining the elevated 1.54" bore height. The clearance ensures compatibility with a wide range of modern tactical and precision optics.

Lightweight at 168 Grams

At just 168 grams, the AUS Mount adds minimal weight to the rifle while providing the rigidity necessary to maintain zero under recoil and impact. The optimized design balances strength with weight reduction, proving valuable for lightweight precision rifle builds and tactical carbines where every gram matters.

Low-Profile Streamlined Design

The low-profile, streamlined design minimizes bulk while maximizing functionality. The clean lines and flush mounting hardware create a professional appearance while reducing potential snag points during tactical operations, vehicle work, or movement through confined spaces.

M1913 Picatinny Rail Compatible

The AUS Mount attaches to any M1913 Picatinny rail, ensuring universal compatibility with AR-15/M4 flat-top uppers, precision rifle chassis systems, and other modern firearms utilizing the Picatinny standard. The proven mounting interface provides secure, repeatable attachment.

Reptilia DOT Mount Heritage

Like the acclaimed Reptilia DOT Mount line, the AUS Mount incorporates the same anti-snag spring-loaded clamp, flush bolt mounting system, single-piece billet construction, and Type III hard anodizing. This shared design language ensures consistent quality and performance across the Reptilia product line.

Made in USA

The AUS Mount is 100% made in the USA, supporting American manufacturing and ensuring quality control throughout production. Domestic manufacturing enables rapid customer support and maintains the high standards expected from Reptilia products.

Lifetime Warranty

Like all Reptilia products, the AUS Mount carries a full lifetime warranty against manufacturer defects. This warranty reflects Reptilia's confidence in their design and manufacturing quality while providing peace of mind for end users investing in precision mounting solutions.

Additional Configurations Coming Soon

Reptilia continues development of additional heights and optic configurations for the AUS Mount line, expanding options for shooters with different optic requirements and mounting preferences. The Reptilia AUS 35mm Mount delivers end-user validated precision mounting—single-piece rigidity with streamlined design for magnified optic excellence.
