The Streamlight Jack-Cap is the multi-function tail cap switch built for the ProTac Rail Mount HL-X Pro long gun light. It's the part that gives shooters operational switch redundancy, supporting both push-button operation directly on the tail cap and a port for a remote pressure switch. For anyone running a rail-mounted Streamlight on a carbine or long gun, this cap is what makes thumb-button activation and tape-switch activation work from the same light. We stock it as a direct replacement or upgrade for the ProTac Rail Mount HL-X Pro platform.
The Jack-Cap (MPN 88130) threads onto the rear of the ProTac Rail Mount HL-X Pro and handles momentary and latching constant-on operation from the push-button. The same cap accepts a remote pressure switch, so a shooter can mount a tape switch forward on the handguard while keeping the button as a backup. This redundancy matters on a duty or defensive setup, where a single point of failure on activation isn't acceptable. The host light it feeds runs 1,000 lumens and 50,000 candela on high with a 447-meter beam, drawing from either two CR123A lithium cells or the rechargeable SL-B26 battery pack. If you're adding remote activation, pair this cap with the matching pressure switch.
Reach for the Jack-Cap when you want both a hand-operated button and a remote tape switch on the same weapon light, or when you're replacing a damaged tail cap on an existing ProTac Rail Mount HL-X Pro. It's a small part that defines how the whole light gets run, so it's worth keeping a spare in the kit. We carry the full line of Streamlight weapon lights and mounting hardware, including M-LOK mounts for the same platform.
