Abstract
Primer adapter assemblies have a body having a cylindrical exterior sidewall adapted to be closely received in a chamber having a chamber diameter, the body defining a central passage including a cylindrical aft portion adapted to closely receive a primer having a primer diameter greater than or equal to the chamber diameter, the body having an aft surface, and a malleable skirt extending aft of the aft surface and defining an installation aperture, the malleable skirt being operable to deform inward to form an opening having a diameter less than the primer diameter, such that a primer in the cylindrical aft portion of the central passage is retained. The skirt may have a tapered cross-section. The skirt may encircle the central passage. The skirt may be concentric with the central passage. The body may include a flange defining the aft surface and having a diameter greater than the chamber diameter.
