The SOLGW Liberty Fighting Barrel is a 13.7-inch 5R-rifled barrel in 41V50 chrome-moly steel, phosphate treated and chrome lined. It has a .223 Wylde chamber with a 1:7 twist and a DLC-coated barrel extension, so it handles both .223 Remington and 5.56 NATO. A mid-length gas system and .750" gas journal with a deep dimple make gas block installation secure.
