ASF (ambidextrous selector, FCD) levers are billet machined in 8620 and black nitrided, they are the same levers that ship with ASF. They're made available separately for ASF users that prefer a different lever for either the left or right side.
As we hold +0.001/0.000 tolerance on ASF's lever and center interface to reduce and largely eliminate lever wobbling, ASF levers are very tight fitting.
Individual ASF levers ship with 2 ASF roll pins (ASF ships with 4 roll pins).
Note: Right side is the ejection port side.
