The Carbon Black rail matches Brigand Arms’ existing high standard for handguard strength and heat rejection, and is capped with hard anodized aluminum rings for optimal impact resistance. It mounts on their standard ultralight barrel nut, and includes multiple M-LOK mounting slots, to accommodate any accessory. These carbon fiber parts are conditioned for stability even during barrel heat cycling, so front iron-sights and other aiming accessories remain accurate during any rate of fire. The 12″ EDGE model weighs only 6.6 oz (INCLUDING barrel nut weight). These handguards are the second lightest rails on the market – second only to Brigand’s original open-structure rails!

AR-10 BARREL NUT INSTALLATION: The large piece of the nut with the gas tube hole in it goes with the flat side towards the upper receiver, and the side with the smooth recess goes towards the muzzle. It does not need to bottom out against the upper. The inner ring – the piece that looks like a bicycle gear -needs to be tightened against the barrel extension collar. While this ring does need to make contact with the barrel collar, it should not be bottomed out against the barrel nut body.
