As normal with Military Fasteners for many years, no issues. I order the parts needed and they send them. Just fair prices and good service.

Ordered on a Monday evening and arrived in New Zealand Friday afternoon. Very good prompt service and the compass was installed on the Saturday after calibration. Thanks Military Fasteners!
