From the Armanov Website:
This spacer for the Dillon casefeeder allows you to quickly raise your case feeder plate without clutch system disassembly. Just put it on the case feeder and insert the plate above the spacer. You will get a 1/4-inch rise (6.35 mm). This can be used for longer pistol cases that turn over or short rifle cases, for example. 300 AAC Blackout with Large Pistol Plate.
