Arisaka Defense Tailcap Adapter for Streamlight ProTac Rail Mount HL-X, precision‑machined 6061 aluminum TA-RMHLX

Product Description

The Arisaka Tailcap Adapter lets Streamlight ProTac Rail Mount HL‑X weapon lights interface with SureFire Scout-style tailcaps and remote switches for improved ergonomics and switching options. Addressing a common HL‑X issue, the adapter includes O‑rings that preload the battery to help prevent flicker under recoil. Precision‑machined from durable 6061‑T651 aluminum and finished with a MIL‑A‑8625 Type III hard coat anodize, this lightweight adapter adds minimal length while delivering reliable performance. Note: this adapter requires a SureFire UE or DS tailcap to function and is not compatible with the ProTac 2.0 Rail Mount lights or the HL‑X Laser model.
