308 AR10740 drop-in 18″

We are offering an AR type barrel chambered for the  .308 Winchester cartridges. These are available in four styles and all are completely finished drop-in type barrels. They are finish-chambered and have a DPMS-style barrel extension installed and the gas port hole drilled for a rifle-length gas system. They also are threaded 5/8″ – 24 at the muzzle. These barrels are not compatible with the Armalite or Rock River Arms rifles.   All versions of this stainless steel AR-type barrel are chambered with a PTG semi-auto match reamer. They are rifled with an 11″ twist 3-groove configuration in .308 Winchester and an 8″ twist 3-groove in .260 Remington. These barrels are also hand-lapped to our internal finish standards. The section forward of the gas block section is engraved: “Lilja AR .308 Win. 11T or Lilja AR .260 Rem. 8T”. The barrel extensions are a DPMS type and these barrels will headspace properly with DPMS type bolts. The gas block and gas port hole are positioned for standard rifle length gas tubes.
