ERATAC Block Mount, 20MOA, Lever – one-piece block mount with quick-release lever and 20 MOA forward cant
If the mount isn't right, even a good scope becomes a source of uncertainty.
The ERATAC Block Mount, 20MOA, Lever is an ERATAC mount with an adjustable quick-release lever for Picatinny/Weaver systems. It connects the scope and weapon 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, forward cant, and clamping system must match the weapon, optics, eye relief, and application. 20 MOA theoretically create an angular difference of approximately 58 cm at 100 m and extend the usable elevation adjustment range at a distance.
Important Classification Note:
Before purchasing, the tube diameter, height, rail standard, forward cant, eye relief, and clamping system must all match.
Before purchasing, check: Picatinny/Weaver rail, scope tube diameter, objective diameter, bolt/charging handle clearance, desired mount height, 20 MOA forward cant, and whether a quick-release lever is sensible for your setup.
What makes this product technically special:
✔ One-piece block mount: maximizes rigidity 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: constructively relevant for ERATAC mounts because mounting points must absorb recoil and clamping forces.
✔ UNIVERSAL interface: for compatible T4/T5 series, accessories such as spirit levels, windage/elevation knobs, or adapters can be mounted close to the optic.
✔ 20 MOA forward cant: 20 MOA theoretically create an angular difference of approximately 58 cm at 100 m and extend the usable elevation adjustment range at a distance.
Why this product?
This mount exists because the connection between the scope and weapon must not be improvised. A scope must sit at the correct height, must not shift under recoil, and must be mounted so that eye relief, stock weld, and weapon operation function correctly. T4 GEN-2 describes not only a model series but also a different operating logic: quick change, permanently bolted solution, ultralight, or T7 with ERA-Grip.
-
Clean optic position: Height and tube diameter are chosen via the variant; this prevents unnecessarily high or too low setups.
-
Defined clamping: Quick-release lever reduces improvisation on a safety- and precision-relevant component.
-
Planned use of forward cant: 20 MOA must match the distance and adjustment range of the scope.
-
System accessories possible: depending on the series, spirit levels, windage/elevation knobs, or adapters can be integrated directly into the ERATAC interface logic.
Instructor's Tip: Mounting errors begin before the first shot
Never mount a scope by eye alone. First, set up stock weld and eye relief, then determine height and position, then align the reticle and tighten screws with the appropriate torque.
For pre-canted mounts, first check if your scope still has enough downward adjustment range at your planned zeroing distance. 20 MOA is useful for many long-range setups, but may be unnecessary at short distances with some scopes.
After every mounting: don't just tighten, but zero in and document the point of impact. Repeatability is not theory – it only shows itself after removal, reattachment, and a control shot.
Our assessment
This one-piece block mount makes sense if you don't want to cut corners on the connection between your weapon and optic. It is particularly suitable for setups where point of impact, mounting height, and reproducible clamping are important: precision rifles, AR10/AR15 platforms, long-range scopes, and hunting weapons with higher optic weight. It is less suitable if the variant does not exactly match the optic or if you are only looking for a simple, inexpensive standard mount for occasional use.
Suitable for:
- Precision and long-range setups with carefully chosen forward cant
- AR and bolt-action platforms with Picatinny/Weaver rails
- Hunting weapons with high-quality scopes and clear mounting height
- Users who consciously choose ring diameter, height, and clamping
Less suitable for:
- Optics with a different tube diameter than the selected variant
- Weapons without a suitable Picatinny/Weaver base
- Users who do not want to check height and eye relief
- Setups where a cheaper, simpler mount is perfectly sufficient
Direct Classification:
✔ ERATAC Block Mount, 20MOA, Lever: strong when quick removal, transport, or optic changes are relevant.
✔ Screw clamping: often more logical if the scope remains permanently on a weapon and tools are not an issue.
The right choice depends not on the brand name, but on the tube diameter, height, forward cant, and clamping system.
Application Scenarios
-
Long Range / Precision: Forward cant and a rigid mount help to make sensible use of the optic's adjustment range.
-
Range and Training: reproducible mounting saves troubleshooting point of impact deviations.
-
Hunting Bolt-Actions: clean height and eye relief are crucial for quick aiming.
-
AR Platforms: mounting height, charging handle clearance, and eye relief must all function together.
Practical Tip: Check objective clearance and head position in reality
Don't just check objective clearance dry. Dust caps, attachments, neoprene covers, or a thicker barrel can suddenly make the seemingly sufficient distance tight.
If the mount is chosen very high, the head position changes. This can be useful with a helmet or hearing protection, but on classic hunting stocks, it can lead to a floating head.
Features & Construction

FAQ
Does this ERATAC mount fit every weapon?
No. It requires a suitable Picatinny or Weaver base and must mechanically match the system, ejection port, charging handle, eye relief, and objective diameter.
Which height should I choose?
The height must match the stock, optic, objective diameter, and shooting stance. Too low can cause contact with the barrel or rail, too high often worsens head position.
What does the forward cant mean in practice?
20 MOA theoretically create an angular difference of approximately 58 cm at 100 m and extend the usable elevation adjustment range at a distance. Important: forward cant provides adjustment reserve, but does not replace proper zeroing and matching ballistic data.
Do I have to re-zero after mounting?
Yes. After every mounting or change to the optic attachment, the point of impact must be checked and the weapon re-zeroed or confirmed.
When is this mount not sensible?
If the tube diameter, height, forward cant, or clamping system do not match your setup. A strong mount is only strong if the variant is correctly selected.
Conclusion: The ERATAC Block Mount, 20MOA, Lever is a technically sound solution for users who consciously choose mounting height, tube diameter, forward cant, and clamping. It is worthwhile when point of impact and system logic are more important than the lowest price. It is not sensible if the variant only roughly fits.
