    This upper ran flawlessly since the first shot. I like the adjustability of the gas block to control overgassing when using supersonics while providing the ability keep the action running while using subs. Works as intended. Suppressed use works great as well. The impression Ive been left with after using this upper is that it is well made, reliable and performs as intended. I would buy another Anderson upper.

    are the chamber and the barrel chrome or nitrite lined, RF85 treated, or are they not treated? I see the bolt carrier is chrome lined.

    • The barrel is Mag phos
      Not chrome lined
      Not RF85 treated

    Put this on an Anderson pistol lowerer, looks great. Could not adjust the gas block, seemed frozen .Got no response from Anderson to inquiry’s f Took to range, ran 60 factory 125 grain, then 20 150 grain, ran flawlessly. However was so over gassed the EXT handguurd worked itself loose. ( was using suppressor) Took hand guard off when cleaning, gas block screw was completely screwed out (open). But no longer frozen. That explains the overgassing. Download from Anderson says you should start with the screw flush, then adjust if over or under gased.
    Love the upper, lost one star for no customer support.
