Phlser Holsters got available the ARC Enhanced WML Switches made for the Surefire X300U (A/B/V), X400U (H, RD, GN), XH30, XH35, and XLV2 with no need for modifications to install these switches... "Improve speed and consistency of weapon mounted light activation with user configurable and modular extended switches.
The Surefire ARC comes as a set of three pairs of switches. All three pairs are over-sized compared to stock and the set includes a Large, XL, and XL blank set. The Large and XL are aggressively textured, improving activation with gloved or wet hands, and requiring less precise dexterity to activate the WML. A blank set in XL size is included for users to carve, modify, or stipple to fit their individual needs.
Large, XL, and stock switches can be mixed and matched, to optimize the WML for right or left-handed use, based on your preferred activation technique, decrease the distance to the switch on some models of firearm, or to simply improve momentary or constant-on activations.
No permanent modifications to the WML are necessary to install the ARC. The original switch caps are easily removed with a small screwdriver or pliers and the ARC switch enhancements press directly on to the switch armature bar. Please watch the instruction video prior to installation. Be aware that the switches are right and left-hand biased, so pay attention to the markings on the ARC switch enhancements.
Depending on the age of your light, manufacturing tolerances, and their intended use, some users may want to apply a tiny dab of adhesive to the switch armature bar as a final step in their installation, after determining their optimal switch configuration.
The Streamlight ARC comes as a pair of two complete switch paddles. One is symmetrical and the other is asymmetrical. Both are larger than stock. The asymmetrical paddle can be reversed depending on which side you prefer to have the longer switch. Kit includes all tools required.
The PHLser ARC for Surefire and Streamlight WML’s fits all popular light bearing holsters.
We accept returns of the ARC in original, intact condition. In the event of defect, we are happy to send a replacement unit. We cannot accept returns of units which have been snapped off the injection tree or installed on lights."
