Tenebraex AGA-ARD Killflash w/ IR Laser Filter for 4x32 Trijicon ACOGs. Very few of these have been released to the public, most of the ones you see on civilian TA31RCO- models are simply regular killflashes that are elongated to replicate the look of ones with laser filters. These ones are the real deal military issue NSN 6650-01-559-3861 for the KILLLASH and NSN 1240-01-540-2890 for the IR filter. The laser filter is threaded on both sides and can be removed, allowing you to convert to a regular killflash whenever you like. Items are brand new in new condition. Only removed from package for photos below.
