Centering gasket for 7.4mm reflector hole?

Hi all,

I’ve been working on modding a maglite with a five -up reflector and XP-L2 emitters. The only trouble is that the reflector holes are an odd 7.4 mm diameter size and finding centering rings has been difficult. The light’s currently got 7mm XM to XP adapter rings in it but the emitters aren’t perfectly lined up. Not a performance issue so much as asthetics but if anyone has a known source of centering rings for 7.4mm reflector holes I would be grateful for the tip.

Thanks much,

Brian
