XS Tritium stripe front sight for the AR features precision machined stress proof steel, a vertical tritium vial, and white outline to provide front sight visibility in any lighting condition. Square top post is 0.105" wide. Each full rotation of front sight gives a 5" shift at 100 yards.
Fits AR front sight housing with front sight detent at 3, 6, or 9 o'clock. Does not fit ARMS back up sight; the blade, front to back, is too long to allow the tower to fold into the down position.
Made in the USA.
