Manufactured in Broken Arrow, Oklahoma, the Quality Manufacturing auto-sear is pre-86 registered with no noted caliber, barrel length or overall length, with a note in the "Additional Description" field noting it as installed in the B item in this lot. The sear has been professionally installed in a trigger pack and is set up for a "0/1/25" selector pattern.

Originally manufactured in 1981, likely as a HK91 before being reconfigured by Fleming as a HK53 style host weapon. Post front and drum rear sights, a slotted flash hider and a checkered forearm. The trigger housing is marked "0/1/25." The "IB" date code and the "HK53" nomenclature are on the left side of the magazine well. The right side of the well is Fleming Firearms marked, with a host number "H0997", which no longer corresponds to the currently installed sear. Fitted with a 2-position telescoping buttstock.
