The Reptilia AGS Mount is a one-piece riflescope mount built for modern bolt-action rifles, holding the scope at a low 1.34in centreline over the rail with 20 MOA of elevation bias built in.
Low over the action, with 20 MOA already in the mount. The turret starts closer to where you need it at distance.
Reptilia describe the AGS as a precision optic mounting solution purpose-built for modern bolt-action rifles, and the low 1.34in centreline is the point of it: the optic sits closer to the bore, which gives a more natural cheek weld on a conventional stock. Dealers commonly list the same mount as 1.3in; 1.34in is Reptilia's own published figure and the one we quote.
The 20 MOA is machined into the mount as a forward inclination, so the scope's internal elevation starts biased for distance and you keep more usable travel at the top of the dial. Reptilia make 0 MOA versions of the AGS as well; those are not part of this listing. It is machined from billet 7075-T6 aluminium in MIL-STD Type III hardcoat anodising and weighs 148 g (5.2 oz). Made in the USA.
Fits riflescopes with a 30mm or 34mm main tube — choose the diameter above — on any M1913 Picatinny rail, which on a bolt-action precision rifle means a rail bolted to the action. This listing is the 20 MOA version only; Reptilia also produce the AGS in 0 MOA, which is a different part and is not sold here. Tube diameter and MOA are both fixed once you have chosen, because a one-piece mount cannot be re-cut. If you want a taller sightline for a chassis with a high adjustable comb, the AUS Mount at 1.93in is the other end of Reptilia's range.

Tracking details are emailed on dispatch. UK delivery only.
You have 30 days from receiving your order to cancel it for any reason, then 14 days to send it back unused and in its original packaging. Faulty, damaged or incorrect items are replaced or refunded and we cover reasonable return postage. Refunds go back to your original payment method within 14 days of receiving the return.
Both numbers describe the same mount. 1.34in is Reptilia's own published centreline height over the rail; 1.3in is the rounded figure most dealers print. We quote Reptilia's figure and note the dealer form so you can match this listing against a catalogue that uses the other one.
It tilts the scope forward by a fixed amount relative to the bore, so at long range you have already used up part of the elevation you would otherwise dial in. That leaves more of the scope's internal travel available at distance. The trade-off is that at very short range you may run low on down-elevation, which is why 0 MOA versions exist for rifles that are not shot far.
No. The tube diameter is a choice, not a set. A one-piece mount is machined to one ring diameter and cannot take an insert, so pick the diameter that matches your scope's main tube from the maker's specification rather than by eye — 30mm and 34mm are close enough to misjudge.
It is built for modern bolt-action rifles, and that is how Reptilia describe it. It clamps to Picatinny, so it will physically fit a flat-top AR-pattern upper, but the low 1.34in centreline is chosen for a bolt gun's stock geometry rather than an AR's. For a gas gun or a straight-pull AR-15 the taller AUS heights usually suit better.
