Vector Optics Red Dot Footprint Guide

What does footprint mean? Footprint is mounting standards for you to install a red dot on a gun. I know that's still abstract concept in some sense. To make it concrete, footprint refers to the 3D pattern on the bottom side of the red dot.

This article may refer other websites or brands for clarification and instruction.

Footprint introduction and clarification

Before introducing the footprint, we would love to share a fun fact about Vector Optics. We use alchohol acroynms to name after them.

Here are several popular footprints. Let us dive in.

Just in case, some people might be curious about why there is footprint and what is its purpose. The red dot sight was developed for pistol. Typically, the width of the red dot is designed to align with the width of the pistol, not too smaller or bigger.

The length of the red dot is decided by the optical design. The sockets at the corners is used to set the red dot on the pistol so that when you take a shot, the recoil wouldn't lead the red dot move around. You may notice a special footprint(VOD) doesn't have sockets, I would explain that further in the article. The bolts are for set screws, ensuring a tight and secure connection between the red dot and the adapter plate.

TEK Footprint

Dimension: 46mm x 28mm / 1.81 inch x 1.1 inch

Pattern: two screw holes in the middle, four sockets at each corner to fit the pin on the red dot sight.

Compatable with: Docter/Noblex® mounting standard

Our red dot sights with TEK footprint: SCRD-19II, SCRD-F19II, SCRD-G19II, SCRD-35, RDSL01, SCRD-40, RDSL16, RDSL18

As depicted below, the back sides of the adapters vary to accommodate different pistols, with plugs designed to fit into rear sight slots of various sizes.

Mounts for rifle: SCRA-67 (for weaver rail on rifle, mount riser), SCFRM-01 (for picatinny rail on rifle, offset), SCFRM-04 (for dovetail rail on rifle, mount base)

MOJ Footprint

Dimension: 45.3mm x 29.5mm / 1.78 inch x 1.16 inch

Pattern: Two sockets at the front side for the pins on the red dot, two screw holes in the middle.

Compatable with: RMR®

Our red dot sights with MOJ footprint: SCRD-36 / SCRD-58 / SCRD-M36 / SCRD-37 / SCRD-59 / SCRD-57 / SCRD-19 / RDSL25, New Frenzy GenII SCRD-64 / SCRD-SM64 / SCRD-T64

Plates for pistol: SCRDM-08 (GLOCK®)

Mounts for rifle: SCRA-71 (for weaver rail on rifle, MOJ footprint red dot, mount riser), SCFRM-02 (for picatinny rail on rifle, MOJ footprint red dot, offset)

MAG Footprint

Dimension: 40.9mm x 26.6mm / 1.61 x 1.05

Pattern: Four sockets at each corner, two bolts in the middle.

Compatable with: RMSc/SMS

Characteristic: It is similar as the TEK footprint but in a compact size. MAG is the smallest footprint which usually applys to mini red dot sights.

Our red dot sight with MAG footprint: SCRD-43 / SCRD-F43 / SCRD-M43 / SCRD-G43 / SCRD-52 / SCRD-53 / SCRD-54 / SCRD-55 / SCRD-62 / SCRD-49 / SCRD-56 / SCRD-50 , New Frenzy GenII SCRD-73 / SCRD-66 / SCRD-68 (will come with an adapter plate fit for RMR/MOJ footprint)

Adapter Plates for Pistol: SCRDM-09 (GLOCK®), SCFRM-16 (MOS to MAG, adapter for GLOCK® with standard MOS), SCFRM-19 (HK® SFP9)

Mounts for rifle: SCRA-73 (for weaver rail on rifle, mount riser), SCFRM-11 (for weaver rail on rifle, cantilever style mount), SCFRM-03 (for picatinny rail on rifle, offset mount).

VOD Footprint

Dimension: 46mm x 30mm / 1.81 x 1.18

Pattern: No sockets or bolt, a cut in the middle for a recoil stopper.

Compatable with: ACRO®

Characteristic: This one is special with no sockets or bolts. It is kind of like a variant of weaver rail. You will need one screw to connect the red dot and the adapter from the bottom side of the red dot. This footprint usually applys to enclosed red dot sight, which you have no place to screw in from the upper side.

Our red dot sight with VOD footprint: SCRD-63 / SCRD-F63 / SCRD-SM63 , New Frenzy GenII SCRD-SM68

Plates: SCRDM-10 (GLOCK®), SCFRM-18 (CZ SHADOW® 2), SCFRM-20 (HK® SFP9)

Adapters: SCFRM-12 (MOS-VOD), SCFRM-13 (MOJ-VOD)

Mounts: SCFRM-14 (for weaver rail, low mount), SCFRM-15 (for weaver rail, riser mount), SCFRM-17 (for dovetail rail, low mount)

RUM Footprint

Dimension: 20mm x 53mm / 0.79 inch x 2.09 inch

Pattern: A cut in the middle, two screw holes on both sides

Compatable with: T-1™/T-2™

Characteristic: This one was also developed for tube sight, which could be applied on rifle.

Adapters: N/A

Mounts: SCPSM-01 (for picatinny rail, cantilever mount), SCPSM-02 (for picatinny rail, low mount)

Our red dot sight with RUM footprint: Maverick series, Scrapper series, Paragon Prism, RDSL27, RDSL28, Centurion 1 x 20

GIN Footprint

Dimension: 27mm x 52mm / 1.06 inch x 2.05 inch

Pattern: Four bolts, two at the front side are smaller than those at the back side

Compatable with: C-More® RTS/STS

Characteristic: This footprint has the biggest dimension. Usually the red dot with GIN footprint is designed for IPSC (The International Practical Shooting Confederation) matches. It would realize the biggest window to provide good field of view. It sometimes also applied on the rifle.

Adapters: N/A

Our red dot sight with GIN footprint: SCRD-65, SCRD-SM44
