Battle Arms Development just officially released their Ultramatch LIGHTRIGID Barrels and they look pretty darn good on paper. These 416R stainless steel barrels feature a proprietary barrel contour and fluting that make them both light in weight (24.6 ounces for the 16″ version) and rigid.
At a glance, they look fairly standard in profile but the .625″ gas block journal is the first clue that this barrel is lighter than it looks! It features a midlength gas system and is dimpled for a gas block set screw. Dimpling is an important feature that both indexes and helps prevent the gas block from spinning due to impact.
The LIGHTRIGID barrels feature a Wylde chamber which works well with both .223 and 5.56 ammo. Both the chamber and feedramps are polished. It has precision button rifled, 6 groove, 1 in 8″ twist rifling. Each barrel is heat treat stress relieved and cryogenically treated.
