Sons of Liberty L9A5RE: The Sons of Liberty Gun Works Loyal 9 A5 Buffer Tube features an extended design with 9 positions of adjustment and is compatible with the Vltor A5 buffer system. The A5 buffer system features an intermediate length buffer combined with a rifle length buffer spring and a longer buffer travel resulting in lower felt recoil and better reliability with overgassed or short barrel rifle builds. Additionally, the heavier buffer weight helps reduce bolt bounce and increases dwell time for a smoother and cleaner running system.
