Primer adapter assembly

A primer adapter for a fuse configured to be received in a device, the adapter comprising:

• a body having a cylindrical exterior sidewall adapted to be closely received in a chamber defined by the fuse and having a chamber diameter;
• the body defining a central passage including a cylindrical aft portion having an aft diameter adapted to closely receive a primer having a primer diameter greater than or equal to the aft diameter of the central passage;
• the body having an aft surface;
• a malleable skirt extending aft of the aft surface and defining an installation aperture, the skirt having an interior diameter greater than the aft diameter, 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 central passage including a flared portion between the cylindrical aft portion and the skirt to facilitate insertion of a primer into the cylindrical aft portion;
• and
• the flared portion having a tapered frusto-conical interior surface free of steps.
