Questions & Answers
Does this have an ipx rating seeing as how the stream light can be ipx7 and the surefire switch too Expert Answer

Arisaka Defense does not state an IPX Rating for the Arisaka Defense Streamlight Protac HL-X Tailcap Adapters. For that information I recommend contacting Arisaka Defense.

Is this compatible with the Streamlight Protac HL #88040? Expert Answer

No, this will not be compatible. This will only work with the HL-X.

Simple and Effective by ShreikingRobots, Verified Owner, June 2, 2024
It's very simple and it does it's job. It's pretty much just the two sets of threads with a free floating transfer bar for the current, so there's very little that can go wrong with it. The only issue with it (which is unavoidable) is that it makes t...

Turning Budget Lights Cool by Ryan Barlitt, Verified Owner, December 14, 2023
Bought this so I could adapt my Streamlight HL-X to a Surefire tailcap since EVERYTHING on the market regarding light switches is for the expensive stuff. Works perfect and have no complaints. It does add on about an inch of extra length overall to t...

Makes you streamlight better by Scott, Verified Owner, May 19, 2023
I bought a streamlight because I didn't want to spend $300 on a surefire. The streamlight comes with a really crappy pressure switch that you have to ziptie to your handguard. I went ahead and bought a unity tactical pressure switch but needed an ada...

Product Info for Arisaka Defense Streamlight Protac HL-X Tailcap Adapters

The Arisaka Tailcap Adapter allows Streamlight Protac Rail Mount HL-X 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.image

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 two different o-rings (one for CR123 cells, one for 18650 cells) which can be placed on the back end of the battery before screwing on the adapter. The o-ring ensures the battery cannot move rearward while firing.
