The TW-Series 1x24 PMMS Red Dot Sight from BSA Optics is a waterproof and shockproof reflex sight made for fast and easy target acquisition and tracking in all weather conditions. The sight comes with a 45° side rail mount. When installed, this mount sets the sight to the side of the rail, leaving a clear line of sight on the rail for scopes or NVDs. This configuration allows for quick transition to the reflex sight with a simple rotation of the rifle for medium or close range use. The Weaver-rail mounting sight has a 3 MOA dot with High and Low brightness levels. Windage and elevation adjustments of 1 MOA per click let you zero the sight. A hard plastic cover is included that covers the whole sight. The PMMS comes complete and ready for use in clamshell packaging.
