A.R.M.S #38 M16 5.56

 A.R.M.S. #38 STD

 Designed to raise an optic 1/2", sized to span the length of a standard M4/M16 upper receiver without extending past/over the delta ring, with an integrated rear sight. This is an early model (pre 2007) #38 in very good condition with 5.56 M16 markings and the wingless swan engraving. The screws do show marks where they were torqued when mounting and there is a slight mark on one of the rail lugs where an optic was mounted. The rear sight mechanism is crisp and works as it should.
