ERATAC block mount 30/34/36 mm – quick release lever – 0–20 MRAD – one-piece block mount with quick release lever and 0–20 MRAD cant

When the mount isn’t right, even a good scope becomes a factor of uncertainty.
ERATAC block mount 30/34/36 mm – quick release lever – 0–20 MRAD is an ERATAC mount with adjustable quick release lever for Picatinny/Weaver systems. It connects scope and firearm as a defined interface – focusing on height, tube diameter, clamping, and point of impact.

With ERATAC, the variant matters more than the name: tube diameter, height, cant, and clamping system must fit firearm, optic, eye relief, and use. 0–20 MRAD means adjustable cant; 20 MRAD corresponds to a calculated 200 cm angular difference at 100 m.

Important note for classification:
Before purchase, tube diameter, height, rail standard, cant, eye relief, and clamping system must match. Check before buying: Picatinny/Weaver rail, optic tube diameter, objective diameter, bolt/charging handle clearance, desired mount height, 0–20 MRAD cant, and whether a quick release lever makes sense for your setup.

What makes this product technically special:
✔ One-piece block mount: maximizes stiffness through a continuous base and reduces mounting errors.
✔ Quick release lever: useful for changing optics or transport when repeatable removal is important.
✔ High-strength aluminum / Mil-Spec Type III: structurally relevant for ERATAC mounts because mounting points must absorb recoil and clamping forces.
✔ UNIVERSAL interface: with matching T4/T5 series, accessories like bubble level, SWK, or adapters can be mounted close to the optic.
✔ 0–20 MRAD cant: 0–20 MRAD means adjustable cant; 20 MRAD corresponds to a calculated 200 cm angular difference at 100 m.

Why this product?

This mount exists because the connection between glass and firearm must not be improvised. A scope must sit at the right height, not shift under recoil, and be mounted so that eye relief, stock contact, and firearm operation work. T4 GEN-2 describes not just a model series but a different operating logic: quick change, screwed permanent solution, ultralight, or T7 with ERA-Grip.

Clean optic position: height and tube diameter are chosen by variant; this prevents unnecessarily high or too low setups.

Defined clamping: quick release lever reduces improvisation on a safety- and precision-relevant component.

Plan cant usefully: 0–20 MRAD must fit the distance and adjustment range of the scope.

System accessories possible: depending on series, bubble level, SWK, or adapters can be integrated directly into the ERATAC interface logic.

Instructor tip: mounting errors start before the first shot
Never mount a scope by eye alone. First set stock contact and eye relief, then determine height and position, then align reticle and tighten screws with the correct torque. For canted mounts, first check if your scope still has enough adjustment range at your planned zeroing distance
downward. 20 MOA makes sense for many long-range setups but can be unnecessary at short distances with some scopes. After every mounting: don’t just tighten, but zero and document the point of impact. Repeatability isn’t theory – it only shows after removal, remounting, and a control shot.

Our assessment

This one-piece block mount is useful if you don’t want to skimp on the connection between firearm and optic. It fits especially well with setups where point of impact, mounting height, and reproducible clamping are important: precision rifles, AR10/AR15 platforms, long-range scopes, and hunting rifles with heavier optics. It’s less useful if the variant doesn’t exactly fit the optic or if you just want a simple, cheap standard mount for occasional use.

Useful for:

- Precision and long-range setups with properly chosen cant
- AR and bolt-action platforms with Picatinny/Weaver rail
- Hunting rifles with high-quality scopes and clear mounting height
- Users who consciously select ring diameter, height, and clamping

Less useful for:

- Optics with a different tube diameter than the chosen variant
- Firearms without a suitable Picatinny/Weaver base
- Users who don’t want to check height and eye relief
- Setups where a cheaper simple mount is completely sufficient

Direct classification:
✔ ERATAC block mount 30/34/36 mm – quick-release lever – 0–20 MRAD: strong when quick removal, transport, or optic change matters.
✔ Screw clamping: often more logical if the scope stays permanently on one firearm and tools aren’t an issue.
The right choice depends not on brand name but on tube diameter, height, cant, and clamping system.

Use cases

- Long range / precision: cant and stiff mounting help use the scope’s adjustment range effectively.
- Range and training: reproducible mounting saves troubleshooting point of impact deviations.
- Hunting bolt-actions: clean height and eye relief are crucial for quick acquisition.
- AR platforms: mounting height, charging handle clearance, and eye relief must work together.

Practical tip: check objective clearance and head position in real conditions
Don’t just check objective clearance dry. Dust caps, attachments, neoprene covers, or a heavier barrel can suddenly make the seemingly sufficient clearance tight. If the mount is chosen very high, head position changes. This can be useful with a helmet or hearing protection but can cause a floating head on classic hunting stocks.

Features & construction

- Series: T4 GEN-2 – determines clamping logic, weight, and accessory interface.
- Mount type: one-piece block mount – very stiff and positionally stable.
- Clamping system: quick-release lever – must fit frequency of change, platform, and working style.
- Cant: 0–20 MRAD – more cant gives more elevation reserve but doesn’t replace a clean zero.
- Variant logic: ring diameter: Ø30 mm, Ø34 mm, Ø36 mm; height (BH): BH20, BH25, BH30, BH22.

Technical data

- Brand: ERATAC / Recknagel – mounts and accessories made in Germany.

FAQ

Does this ERATAC mount fit every firearm?
No. It requires a suitable Picatinny or Weaver base and must mechanically fit the system, ejection port, charging handle, eye relief, and objective diameter.

Which mounting height should I choose?
The height must fit the stock, optic, objective diameter, and cheek weld. Too low can cause contact with barrel or rail, too high often worsens head position.

What does the cant mean in practice?
0–20 MRAD means adjustable cant; 20 MRAD corresponds to a calculated 200 cm angular difference at 100 m. Important: Cant provides adjustment reserve but does not replace proper zeroing and correct ballistic data.

Do I need to re-zero after mounting?
Yes. After every mounting or change to the optic mount, point of impact must be checked and the firearm re-zeroed or confirmed.

When is this mount not suitable?
If barrel diameter, height, cant, or clamping system do not fit your setup. A strong mount is only strong if the variant is correctly chosen.

Conclusion: ERATAC block mount 30/34/36 mm – quick release lever – 0–20 MRAD is a technically clean solution for users who consciously select mounting height, barrel diameter, cant, and clamping. It’s worth it if point of impact and system logic are more important than the lowest price. It’s not suitable if the variant only roughly fits.
