The RTS2 features a large glass lens, shake to wake, hardened electronics, and uses a CR2032 lithium battery contained in a side load battery tray which permits battery replacement without dismounting the sight; this eliminates the need for re-zeroing when replacing a battery. The RTS2 has a 10 position push button manually operated intensity switch and is equipped with an optional removable Picatinny / Weaver Rail Mount so the sight can be rail mounted or used in direct mounting applications. Available with a 3, 6, 8, 10 or 12 moa dot for use in a wide range of applications, the RTS2 mounts directly or uses separate mounting rails or adapter plates to attach to todays most common firearms.
