Shield SMS2 Mini Sight Glass Lens
The SMS2 is the latest incarnation of the SMS, with many improvements over the first model, and further improved with this the glass lensed model. Sold under other brand names for many years, you may know the Shield Mini Sight as the Firepoint, Tasco Optima, Trijicon RedDot or JPoint.
Also available with base clamp to allow mounting to any Weaver or Picatinny mount. Do not confuse these sights with the cheap Chinese rubbish for £20 or £30. These are rugged, well made and accurate sights. So tough they can actually be mounted on an auto loading shotgun or the slide of a pistol!
