.308 Extension Tube
LMT® .308 receiver extension tube
LMT offers its 308 receiver extension, or buffer tube, for sale to customers for their builds. This tube is approx. 3/4″ longer than a standard AR-15 style buffer tube. This allows for usage of standard length buffers like the H3 equipped in our factory MWS rifles and carbines. Our tubes are black anodized aluminum with a dry film lubricant (DFL) applied for enhanced performance.
