Vector Optics SCFRM-11 Polymer Mount with MGT (SHIELD) Footprint, 21mm Picatinny, h=28mm – Practical Classification
Optics are only as good as their interface.
The Vector Optics SCFRM-11 Polymer Mount with MGT (SHIELD) Footprint, 21mm Picatinny, h=28mm is a mounting or adapter part for Vector Optics setups where height, footprint, and rail must fit together precisely.
This is precisely where most errors occur in practice: incorrect footprint, incorrect height, incorrect rail – resulting in poor cheek weld or point of impact.
Why this product?
✔ Check interface carefully according to SKU, footprint, and rail
✔ Consider Picatinny/Weaver, 11 mm Dovetail, or specific adapter logic
✔ 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
- Consider Picatinny/Weaver, 11 mm Dovetail, or specific adapter logic
- Height determines head position and sight picture
- Always check fit and point of impact after mounting
- Useful for Red Dot, scope, riser, or adapter setups
- Not a universal part for every system – compatibility is mandatory
Our Assessment
Our assessment: This product does not 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, you'll end up buying twice.
Instructor Tip: read the interface first, then buy.
Check three things: What rail does your weapon have? What footprint does your sight have? What height do you need for your cheek weld? Only when 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 red dot sights, optics, or accessories correctly.
Not suitable for: Not suitable if the footprint, height, or rail interface does not clearly match the existing setup.
Features & Operation
- Do not confuse footprints like TEK, MOJ, MGT, VOD, or RUM
- 11 mm Dovetail is not Picatinny
- Low mount for flat systems, high/riser mount for AR-like cheek welds
- 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 – do not classify it as uncompromising authority/duty equipment.
FAQ
What is this mount used for?
It creates the mechanical interface between the weapon, rail, red dot, or accessory. Footprint, 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, .22 LR systems, and certain hunting/sporting firearms.
Why is height important?
The height determines your head position and whether you quickly get a clean sight picture. Too high or too low costs speed and comfort.
Do I have to zero 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: choose not only by data sheet, but also by use, mounting, target distance, and real application.
