The Trijicon ACOG Reflex Sight and the Meprolight Mepor 21 Sight both use light gathering fiber optics and tritium to produce a dot sight that doesn't require batteries to operate.
On the one hand, you don't have any batteries to worry about or any switches to fool with.
On the other hand, tritium is only good for about 10 years.
Nonetheless, I'm intrigued. Has anybody had any experience with either of these gizmos?
Their simplicity is attractive, but would I wind up with a worthless hunk of glass in 10 years, or can the tritium be somehow economically recharged?
Any information or advice would be appreciated.
