I have 1 ARMS #40 BUIS
I purschased this from a member here as a like new unit, well.....
The unit was kyrloned in a OD green. and a fair amount of that paint has come off. COsmetic only, unit functions. The aperature rings are stiff, but the do turn back and forth.
I have since gone with a 40L and no longer need this.
First $45 gets it shipped US Mail
