         11 . The apparatus of  claim 1 , wherein the rotatable drive interface is defined by a first retaining part of the at least two retaining parts; and
 wherein the portion of the retaining assembly comprises at least a portion of a second different retaining part of the at least two retaining parts.   
     
     
         12 . The apparatus of  claim 11 , wherein the first retaining part is rotatable around an axis of rotation, using the rotatable drive interface, and wherein the rotatable drive interface is drivable using a tool oriented perpendicular to the axis of rotation. 
     
     
         13 . The apparatus of  claim 11 , wherein the second retaining part comprises a bottom-up fastener having a head and an end opposite the head, wherein the head is located further from the optic sight than the end when the received portion of the retaining assembly is within the slot. 
     
     
         14 . The apparatus of  claim 13 , wherein the optic sight includes a pocket to receive the first retaining part. 
     
     
         15 . The apparatus of  claim 1 , wherein the optic sight comprises a closed emitter optic sight including an environmentally-isolated cavity and a beam emitter located therein. 
     
     
         16 . An optic sight installable on a firearm assembly using a retaining assembly, the retaining assembly including at least two retaining parts, at least one of which includes terminal ends and a length in which the length defines a rotatable drive interface, the optic sight comprising:
 a pocket defined by a body of the optic sight; and   the pocket capable of receiving a portion of the retaining assembly in a partially assembled state, and allowing rotation of the received portion of the retaining assembly;   wherein, while the received portion of the retaining assembly is within the pocket, the rotatable drive interface is usable for securing the optic sight on the firearm assembly or the adapter.
