Editing Delta Archery (section)

=== Original Defiant design ===

The original Delta Defiant was mechanically distinct from the production Defiant.

Its experimental operating system used pneumatic pressure to recock the marker after firing, while retaining mechanical trigger control.

The ram assembly was incorporated inside the receiver instead of being positioned externally.

The prototype also employed a low-pressure pneumatic system and a valve arrangement intended to improve gas flow.[7][8]

Although the design reached advanced prototype testing, the available historical records do not establish commercial production.
