Scout Light Tail Cap Connection

HotButton and ModButton have a much higher quality Scout light plug than the Surefire brand. If you have problems with Surefire pressure switch not working, we highly recommend you checking out these products.

The angled connection to account for bending, and it also tucks in the wire slightly more.

Take a look at this:

  • Thicker wire to ensure the light delivers the lumen output
  • Tighter scout light tail cap connection

ModButton Combo

original modbutton and modbutton lite combo

ModButton works the same way as the HotButton, and the wire specs are the same.

Available in 4.5" cable length - For almost all use cases. 7" may be too long.


The Surefire scout remote switches definitely work, but the only down side is the rubberized pressure switch doesn't stay tight on the M1913 rail, and it comes off easily.

Laser Lead Connection

surefire and laser plugs

For a rock solid laser plug connection, it's time to ditch the Surefire SR07-D-IT! It works, but it gets lose under recoil.

The laser plug is also designed by Unity Tactical that provides a much tighter connection, so the wire doesn't come off the laser easily due to vibration and recoil. 

ModButton's Crane style laser plug is the best, and it works for:

  • PEQ15
  • All Steiner DBAL products
  • BE Meyer MAWL
  • Wilcox RAIDx laser

Available in 4.5" cable length - For almost all use cases. 7" may be too long.

The user can customize the ModButton laser switch on either Flat, Angled or Dual Ramp housing unit (HRF Concept). 

Pressure Switch Button

All of them have great rubberized pressure switch surface. They are big enough for people wearing gloves to operate, and feels very tactile.

  • Pressure switch gives positive feedback
  • Large area to press along the handguard for users wearing gloves
  • However, it can come off the rail easily

The Surefire SR07 pressure switch provides a large area for the user to activate momentary light, and it also features a constant on button.

The indexed dot helps the user differentiate between light and laser activation.

Surefire sr07-d-it pressure switch surface

The Surefire SR07-D-IT is a dual switch, but it doesn't feature constant on mode. This is where mixing HotButton surefire plug and ModButton laser plug together might be a better option. 

The HRF Concept Dual Ramp provides the user ergonomic improvement over two flat buttons. The opposing angles of the buttons and center gap allow users to differentiate both buttons with ease even in low light. 


ModButton has the best modularity as far as mounting it on different housing units:

  • Flat
  • Angled
  • Dual switch unit
  • MLOK 

Integrate with Unity Tactical's offset scout light mount to minimize rail space usage and to keep things compact, and it also increase the accessory layout options on PDW and subguns like the KRISS Vector & CZ EVO (See pictures below)

HotButton is very ergonomic, but the user can't customize it like the ModButton.

SureFire switches only work on M1913 rail. It can be angled either.

The Surefire SR07 and SR07-D-IT have been on the market for a very long time. They work, but the only problem is that they don't stay on M1913 rail tight.

ModButton is light, and it's made from injection molded plastic that's fully potted to provide protection against harsh use.

HotButton is also very light, and it's made from aluminum. It's a very integrated design
