Product Highlights
  • Designed for M4/M16/AR15
  • 5 mW 635 nm Visible Pointer
  • A.R.M.S. Throw Lever Mount

The LDI OTAL Laser Designator is designed for military and Law Enforcement applications. This rugged unit mounts behind the front sight cage on the AR-15, M-16 and M-4 style rifle on a Picatinny rail. The laser is offset to the axis of your rifles bore; it projects the beam around the side of the front sight post. This OTAL attaches to a Picatinny rail by means of an A.R.M.S. Throw Lever Mount. This mounting solution is fast, repeatable, and versatile.

The OTAL delivers a tactical level 635 nm visible laser beam to your intended target instantly upon activation. Momentary or constant-on operation of the pointer is made possible via a single or double tap to the pressure pad switch.

The OTAL is only available to US military and law-enforcement agencies
