We mentioned the Manticore Arms Arclight Tavor fore-end earlier, and sure enough, there's an even more feature-packed version available.
The Arclight XTL Tavor fore-end replaces the standard Tavor fore-end in the same manner as the Arclight previously covered. The XTL, however, allows not only more attachments, as rail space increases to 11 slots with the ARC LOK system, but also a separate weaponlight carefully built into the fore-end and operated via a pressure switch. Handy slots allow you to rout wires from your light to a fore-grip for instant activation.
Installation is simple and takes little time, and the only tools needed are the allen wrenches (included) and a Philips screwdriver (not included). You'll have to supply your own weaponlight, of course; any standard 1-inch diameter flashlight will do. Having a unit that can replace an endcap with a pressure switch is necessary, as well.
Two sections of rail are available (standard on the "Fully Loaded" trim): a 5-slot section and an 11-slot section. There is mounting space on the Arclight XTL to mount both slots if desired, accommodating (for example) a rail-mounted laser in front and an angled fore-grip behind it.
MSRP: $175 ("Naked" trim), $235 ("Fully Loaded" trim). Available in black, flat dark earth and OD green.
