Breek Arms' mission is to provide quality parts at competitive prices. 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.image
