ARC, Enhanced WML Switches, X300


In stock

SKU: PHLARC01 Categories: ,


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 firearms, 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.

    Love the new switch covers but the original ones were a PITA to get off, might have slightly bent my arms.

    Easy to install and makes activating my light a lot easier.

    Installed the longest extension on my X300 that’s currently on my Glock 41. However I only installed the extension on the left side because the longest one hits my trigger finger.

  11. Ryan says:

    Excellent and easy to install upgrade for the surefire X300. I appreciated the fact this set comes both the long and medium sized enhanced switches so I was able to test which one suited my grip the best.

  12. Lou Williams says:

    great product well designed good for replacing the OEM switch arms

  13. Jesus S. says:

    This item is money, second one I’ve bought for my other weapon light.

  14. David says:

    Your product is just fine. I do not like the switch on the surefire for a handgun. It takes the support hand to operate the switch

    The sIg foxtrot is much more user friendly

    May try the stream light next time.
