Will the Era-Tac T1004-0018 ring mounts hold zero under heavy heavy-calibre recoil in outback hunting conditions?

Yes, these mounts are built to strict military specifications and are 100% recoil-proof up to .50 BMG. The self-locking quick-release steel levers feature a spring-loaded lock catch to prevent accidental opening in dense Australian brush, ensuring reliable return-to-zero when removing and reattaching your optic.

Are these mounts suitable for extreme long-range target shooting beyond 1,000 metres?

The T1004-0018 features a 0 MOA / 0 MIL built-in inclination, making it ideal for standard engagements. However, if you are targeting extreme long-range distances beyond 1,000 to 1,500 metres where your optic elevation travel may run out, you should instead consider an Era-Tac cantilever block mount with a fixed forward cant of 20 to 40 MOA or an Adjustable Inclination mount.

Do I need any special adapters to mount these on a standard Picatinny rail, and can I attach accessories directly to the rings?

No adapters are needed if your rifle is equipped with a standard MIL-STD-1913 or STANAG 4694 Picatinny rail. Additionally, each 25 mm ring top features the ERA-TAC UNIVERSAL-Interface with pre-drilled threads, allowing you to directly attach tactical accessories such as the Era-Tac Aluminum Scope Ring With Universal Interface 34mm, secondary red dot sights, or bubble levels.

What is the height of these rings, and are they suitable for an ultralight mountain hunting setup?

The base height is 18 mm, measured from the top surface of the Picatinny rail to the bottom of the scope tube. With a total weight of 285.0 g for the pair, they are robust tactical units; if you are building an ultralight mountain hunting setup where every gram matters, Era-Tac’s Ultralight series or the standard nut-fixed version weighing 245 g may be a better fit.

34mm Scope Mounts - Era-Tac T1004-0018

The Era-Tac Two-Piece Ring Mounts 34mm with Lever Base Height 18mm (T1004-0018) are heavy-duty tactical mounting rings engineered to mount 34 mm main tube rifle scopes to standard MIL-STD-1913 Picatinny and STANAG 4694 rails. Manufactured from 7075 aircraft-grade aluminium with a Mil-Spec Type III hardcoat anodised matte black finish, this two-piece mounting system uses rust-proof, hardened steel quick-release levers to provide repeatable return-to-zero capability. The separate two-piece architecture accommodates varying action lengths and bridges while leaving top ejection ports clear on bolt-action platforms.

ERA-TAC UNIVERSAL-Interface: Pre-drilled threaded interface points located on the top of each 25 mm wide ring cap allow direct attachment of auxiliary optical accessories, such as secondary red dots and angle cosine indicators.
Two-Piece Flexibility: Independent ring placement easily adapts to long-action receiver dimensions and non-standard action bridge spans.

Who is the Era-Tac Two-Piece Ring Mounts 34mm With Lever Base Height 18mm for?

Precision long-range tactical shooters — seeking repeatable quick-detach capability on full-size tactical setups via a 34mm scope ring mount with a low 18 mm base height and a solid 285.0 g footprint.
Heavy-calibre long-range hunters — utilizing heavy-recoil magnum rifles up to .50 BMG where a 0 MOA / 0 MIL inclination setup and an 18 mm base height provide reliable receiver and objective clearance across open ejection ports.

Less suitable for: Shooters targeting extreme long-range distances beyond 1,000 to 1,500 metres where optic elevation runs out (who require a cantilever block mount with 20 to 40 MOA forward cant or an adjustable inclination mount), weight-sensitive mountain hunters needing an ultralight setup under 285.0 g (who are better served by dedicated ultralight or standard nut-fixed rings weighing 245 g), and rifles with European 11 mm or 17 mm dovetails or proprietary Tikka/Sako integral rails without a Picatinny adapter.
