The Reptilia AUS Mount is a one-piece riflescope mount for 30mm 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 158 g (5.6 oz) and takes a 30mm scope tube.
39mm is Reptilia's own figure and works out at 1.535in, which the trade lists as 1.54in bore height — the same mount described two ways. It is the lowest of Reptilia's AUS heights and suits a rifle with a conventional comb, where you want the scope close to the bore and your head low on the stock. On a bolt gun that is the classic set-up: less holdover geometry to think about at close range, and a natural cheek weld without a raised comb. Made in the USA.
Why shooters choose the AUS Mount 30mm 1.54"
-
30mm 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
-
158 g (5.6 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 30mm 1.54" fits
Fits riflescopes with a 30mm 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 30mm mount at 1.70in and 1.93in bore heights, and the same 1.54in height for 34mm and 35mm tubes.
