Have you been wanting to upgrade the plastic “Glacier Guard” hand guards on your AR but don’t want to add a bunch of weight and don’t want to go with another plastic hand guard? ERGO Grips might have the perfect solution for you. They just introduced their new UltraLight Z KeyMod Drop-In rail. It is a 2-piece design that mounts in place of the standard hand guards without any disassembly. The new UltraLight Z KeyMod rail is machined from 6-series Aluminum and comes in a full size model as well as a slim model that doesn’t sit as low below the barrel. You’ll find KeyMod slots at 3, 6 and 9 o’clock and a full picatinny section at 12 0’clock. The UltraLight part of the name comes from the 5.6 ounce weight which is lighter than say a Magpul MOE carbine length handguard which is polymer. These are available for purchase now in Matte Black (hard coat anodized) or in Dark Earth or OD Cerakote. Purchase at the links below.
