We are offering an AR type barrel chambered for the .260 Rem & .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.

We make a variety of profiles for non-drop-in AR type rifles including the AR-15, AR-10 and M-4's. To see a listing of our AR type contours in a .pdf file - Click Here These other contours are not available from us as finished drop-in barrels; only those contours listed above.
