The Reptilia AUS Mount is a one-piece riflescope mount for 35mm tube scopes, holding the optic at a 39mm (1.54in) bore height on any M1913 Picatinny rail.
One tube diameter, one bore height, one machined body. There is nothing here to shim, stack or align — that work was done on the mill.
Reptilia describe the AUS Mount as the culmination of a two-year development programme driven by an end user group. It is machined from billet 7075-T6 aluminium, finished in MIL-STD Type III hardcoat anodising, and clamps to the rail through an anti-snag spring-loaded nitrided steel clamp. This version weighs 168 g (5.9 oz) and takes a 35mm scope tube.
35mm tubes are the large end of the precision market, used where a scope needs even more internal elevation than a 34mm body can carry. Very few mounts are cut for them, which is why this one exists as its own part rather than as a 34mm mount with inserts. Reptilia's 39mm height — 1.535in, sold in the trade as 1.54in — keeps a large scope as close to the bore as its objective allows. Made in the USA.
Why shooters choose the AUS Mount 35mm 1.54"
-
35mm tube, fixed — machined for one ring diameter, so the scope beds on metal rather than on shims
-
39mm (1.54in) bore height — chosen at the mill, not adjusted on the rifle
-
One-piece body — rings and base are the same part, so there is no base-to-ring joint to move
-
168 g (5.9 oz) — billet 7075-T6 aluminium in MIL-STD Type III hardcoat anodising
-
Spring-loaded steel clamp — stays open while you place the mount, then closes flush and anti-snag
What the AUS Mount 35mm 1.54" fits
Fits riflescopes with a 35mm main tube, on any M1913 Picatinny rail — the flat-top receiver of a bolt-action precision rifle, a rail-topped action, or a flat-top AR-pattern upper. Reptilia state that an objective up to 77mm will clear a flat-top Picatinny rail at this height. Tube diameter and bore height are both fixed on this listing and neither is adjustable, so measure your scope's main tube and decide your height before ordering. Reptilia make the same 1.54in height for 30mm and 34mm tubes. There is no 35mm AUS mount at 1.70in or 1.93in in this range.
