Well Kelley's posi-dents aren't so positive. Their hole is 10/32 which Merit offers. I like how in the heat of whatever heat Your in You don't have to take off gloves and hope and pray the little detent went in perfectly. With Merit the ap size changes without changing position of said ap. If that works as they say I'm all in
I shot a Merit across the course for years, and loved it.
Let us know how you make out.
If interested in selling off that imprecise Kelly, lemme know, I have a sight here that could use that one.
Thx,
