The Lewis Machine & Tool MWS rifle systems come with a wealth of enhancements like a monolithic handguard and upper receiver and a chrome lined barrel with a durable barrel nut lock-up system. Now you can build your own with the MWS .308 Barrel. This barrel is 16” and comes with a midlength length gas system with straight gas tube already installed. Ready to go from the factory, all you need to do is drop this barrel into the MWS upper receiver, torque it down and you are ready for the range. The medium profile barrel features a Phosphate outer finish and a chrome lined bore that will last thousands of rounds. Attached to the end is an A2 flash hider.
