This adapter requires the use of a Surefire UE or DS tailcap to function.
The Arisaka Tailcap Adapter allows Streamlight Protac Rail Mount 1 and 2 lights to use Surefire Scout tailcaps and remote switches. In particular, the Protac Rail Mount lights can now be used with the Surefire SR-D-IT and TNVC/Unity TAPS dual switches, which are commonly paired with laser/illuminators like the ATPIAL and DBAL series.
One of the main flaws of the Protac Rail Mount lights is also addressed: Streamlight did not design a front battery spring into the light, so under recoil the battery can come off the front contact and cause the light to flicker or blink. To help prevent this behavior the adapter includes a removable buffer o-ring on the front face which ensures the battery cannot move rearward while firing.

Surefire UE (Newest version with black ring where the remote plugs in. The old gray ring version is not compatible)
Compatible Remotes (with Surefire UE or DS tailcap):
Unity Hot Button
Modlite Modbutton Lite (Surefire plug)
Streamlight's TEN-TAP Programming is still fully functional with the use of Surefire tailcaps and remote switches in combination with the Arisaka Tailcap Adapter. The current setting is not altered unless purposefully changed just like using the stock Streamlight tailcap.
