SIG Sauer Optics

SIG Sauer's Electro-Optics line brings serious engineering and strong value across red dots, magnifiers and rifle scopes — from the hugely popular ROMEO5 to the TANGO LPVO range and the laser-ranging SIERRA6BDX. At Xtreme Tactical we stock SIG Sauer optics for rifle and pistol, dispatched from the UK.

Shop SIG by type: ROMEO red dot sights, SIG rifle scopes including the TANGO-MSR and TANGO6T LPVOs, sealed models in our enclosed red dot sights, and JULIET magnifiers that pair with most ROMEO dots.

See best optics for a straight-pull AR and best red dot sights under £300.

Frequently Asked Questions

What is MOTAC?
SIG's Motion-Activated Illumination wakes the dot when the optic moves and sleeps it when idle, which greatly extends battery life between outings.

Which ROMEO for my rifle?
The ROMEO5 is the value all-rounder; the ROMEO4 and ROMEO8 series add a sealed housing that copes better with rain and mud. Browse them all in ROMEO red dot sights.

Will a SIG scope fit my rifle?
Most need 30 mm or 34 mm rings on a Picatinny rail. For a Tikka, Sako, CZ, Blaser or Weaver-based action see our mount fitment guide, or 11 mm dovetail mounts for a rimfire.
