Breek Arms AR-15 RG2-S MLOK Handguard 4.25in Black. Our newly developed RG2-S (Rugged Rail Mod2) Handguard line up is an evolution from our previous lineup. Our Patent Pending locking mechanism uses a wedge block system that puts equal pressure all the way around the barrel nut. This gives you better harmonics and a much stronger mounting solution especially when you're putting pressure on the end using a bipod or sling. The Newly Released RG2 handguards were developed specifically for suppressor builds each length is designed to fit common barrel length and leave room for all types of quick attach suppressor mounting solutions. The skeletonized design shaves as much weight as posssible without sacrificing the integrity of the handguard. All edges are chamfered blasted then Type 3 Hardcoat anodized for a smooth feel.
