20mm AAI phase 3 caseless

[SG500]

A recent addition. Made by AAI as a caseless round. Phase 3 of the project.

According to the previous owner likely related to OICW (Objective Individual Combat Weapon) or OCSW ( Objective Crew-Served Weapon).

Overall length 85mm.

If anyone has any further information please let me know.

All inert and unprimed.

Dave.

Beg pardon, I know resurrecting a thread can be viewed as taboo on some websites, but would there happen to be documentation about the AAI OICW/OCSW ammunition developments? Because I can't really anything on this particular cartridge.
