Sig Sauer MCX Virtus Patrol Rifle

Sig Sauer MCX Virtus Patrol Rifle

The Sig Sauer MCX Virtus Patrol Rifle is one of the most adaptable rifles on the market, with over 500 configurations available. The 16” barrel is cold-hammer forged and completely interchangeable by the user. For the shooter interested in customizing their own AR, the possibilities of the MCX Virtus are virtually inexhaustible.

True to their reputation, Sig Sauer provides a solid foundation for these configurations. This compact firearm reduces recoil thanks to an internal recoil system, and the Matchlite Duo trigger increases accuracy.

The MCX Virtus Patrol Rifle is part of Sig Sauer’s MCX family, which all use short-stroke gas piston systems for lower recoil and better reliability. They are a newer line, first appearing in 2015 and growing in popularity ever since.

MCX Virtus Patrol Rifle: Modularity

The Sig Sauer MCX Virtus Patrol Rifle has a standard build with few variations from the manufacturer – but it is specifically built to give as many options as possible to the user in designing their own personal firearm.

But what exactly does this modularity entail? What changes might a consumer be able to make to this weapon?

Following is just some of the parts that can be changed on the Sig Sauer MCX Virtus Patrol Rifle:

  • Handguards
  • Pistol Grips
  • Buttstocks
  • Barrels (including intercaliber)
  • Sights and optics
  • Suppressors

There are also aftermarket kits available to tailor the MCX Virtus toward three popular configurations:

  • Patrol
  • SBR
  • Pistol

These three primary variations primarily change the barrel, grip, and stock for a new version of the firearm. This means that a single firearm can be transfigured quickly and with minimal technical skill from a rifle with a 16” barrel to a pistol that can be fully concealed for self-defense on the go.

With 500 configurations, these are just a few examples of where users can take the MCX Virtus Patrol Rifle.
