Like new condition Olympic Arms OA-93  pistol with original carrying case, pin, users manual and paperwork. Second owner and I believe its unfired.  OAP is the prefix with a two digit serial OAP001X.  Very unique weapon that doesn't require a buffer tube like in most other Ar pistols so makes it very compact. Weapon that will be at the top of banned list as the current gun laws are headed towards.  Last pic is just to show it with a high cap mag and Aimpoint sight both NOT included. 
$2500 cash
