Claim 9:
10. A retaining device securable along an associated firearm and selectively operable to engage and retain an associated bolt assembly of the associated firearm in a substantially-fixed position for an indeterminate period of time with the associated bolt assembly including an associated bolt carrier with an associated carrier passage, said retaining device comprising:
a mounting plate dimensioned for securement on an associated receiver of the associated firearm with the associated receiver including an associated receiver wall at an associated distance from the associated bolt assembly, said mounting plate having a thickness, a length and a width, said mounting plate including a first side surface portion and a second side surface portion facing opposite said first side surface portion with said first and second side surface portions spaced apart from one another in a thickness direction and said second side surface portion dimensioned to abuttingly engage the associated receiver, and said mounting plate including a pin-receiving passage extending therethrough in said thickness direction; and,
a retention pin having a longitudinal axis and extending axially from a first end toward a second end, said retention pin extending through said pin-receiving passage such that said first end projects outwardly from said mounting plate beyond said first side surface portion, said retention pin supported on said mounting plate for axial displacement relative thereto between:
a first pin position in which said second end of said retention pin extends outwardly beyond said first side surface portion of said mounting plate a first distance in said thickness direction such that in said first pin position said second end of said retention pin is engageable with the associated carrier passage of the associated bolt carrier of the associated bolt assembly to retain the associated bolt assembly in a substantially-fixed position relative to the associated receiver; and,
a second pin position in which said second end of said retention pin is disposed a second distance from said first side surface portion that is less than said first distance such that in said second pin position said second end of said retention pin is disengageable from the associated carrier passage of the associated bolt carrier of the associated bolt assembly.
