The Heinie Classic design is the original rear design produced by Heinie. It is CNC machined from Bar Stock for durability. It features a serrated rear face and the legendary single tritium insert (for low light and night time shooting) that aligns vertically with front sight tritium insert (when used as a set). This vertical alignment is proven to be faster and less confusing for the human eye than the traditional horizontal alignment.
No fitting or modifications required for installation.
Not for use with suppressors.
