Vector Optics SCRA-71 Mount with MOJ (RMR) Footprint, 21mm Picatinny, h=28mm – Practical Classification
Optics are only as good as their interface.
The Vector Optics SCRA-71 Mount with MOJ (RMR) Footprint, 21mm Picatinny, h=28mm is a mounting or adapter part for Vector Optics setups where construction height, footprint, and rail must fit together perfectly.
This is precisely where most mistakes happen in practice: wrong footprint, wrong height, wrong rail – and ultimately the aiming position or point of impact is incorrect.
Why this product?
✔ Check interface carefully according to SKU, footprint, and rail
✔ Observe Picatinny/Weaver, 11 mm Dovetail, or specific adapter logic
✔ Construction height determines head position and sight picture
✔ Always check fit and point of impact after mounting
Key Features
- Check interface carefully according to SKU, footprint, and rail
- Observe Picatinny/Weaver, 11 mm Dovetail, or specific adapter logic
- Construction height determines head position and sight picture
- Always check fit and point of impact after mounting
- Suitable for Red Dot, Rifle Scope, Riser, or Adapter setups
- Not a universal part for every system – compatibility is mandatory
Our Assessment
Our assessment: This product doesn't solve an abstract accessory problem, but a concrete setup problem. If the interface is correct, your system will be faster, cleaner, and more repeatable. If it's not correct, you'll buy twice.
Instructor Tip: read interface first, then buy.
Check three things: What rail does your weapon have? What footprint does your sight have? What construction height do you need for your aiming position? Only if these three points match is the mount useful.
Who is it suitable for?
Suitable for: Suitable for sport shooters and hunters who want to set up their Red Dot, optics, or accessories properly.
Not suitable for: Not suitable if the footprint, construction height, or rail interface does not clearly match the existing setup.
Features & Operation
- Do not confuse footprints such as TEK, MOJ, MGT, VOD, or RUM
- 11 mm Dovetail is not Picatinny
- Low mount for flat systems, high/riser mount for AR-like aiming positions
- Tighten screws evenly and check after the first shots

Scope of Delivery
Note:
Always check compatibility, mounting, secure fit, and function before use. For optics- or point-of-impact-relevant parts, shoot a control series after each mounting. Vector Optics is a strong budget to mid-range solution for civilian applications – not to be classified as uncompromising official/duty equipment.
FAQ
What is this mount used for?
It creates the mechanical interface between weapon, rail, red dot, or accessories. Footprint, construction height, and mounting interface are crucial.
What is the difference between Picatinny, Weaver, and 11 mm Dovetail?
Picatinny/Weaver are 21 mm rails for many sport and hunting setups. 11 mm Dovetail is often used for air rifles, small caliber systems, and certain hunting/sporting weapons.
Why is construction height important?
The construction height determines your head position and whether you get a clear sight picture quickly. Too high or too low costs speed and comfort.
Do I need to shoot a control group after mounting?
Yes. Any change to the mount or optics should be confirmed with a point of impact check.
Is the mount universal?
No. Footprint, rail, and device must match. Always check SKU, interface, and compatibility before purchase.
Especially with Vector Optics, the correct classification determines the benefit: Don't choose based on the datasheet alone, but on use, mounting, target distance, and real application.
