Leupold Alumina Flip-Back cap would fit on other brand ?

[jujutsu]

HI, first my english skills are not top notch so, be gentle !
I recetrly bought a wonderful Trijicon 3-9x40mm. But i really, really like the ALUMINA FLIP CAP from leupold.
Does anyone got some try with these, even with other scope brands.
My reserach for the moment are 50/50, some said yes and some no... i ask Trijicon and Leupold → no answer (I try...)

trijicon specification:

If someone, even a dealer got some alumina flip cap, please try it on all scope you have, make a list and share it.
Leupold can be happy to sell more alumina stuff.
Thanks everyone and please don't tell me about the Butler Creek, yes its good stuff !

Trijicon accupoint 3-9x40mm.
Specification •G (objectif Ø) = 1.90 inch or 47mm →(1.90 inch = 48.26mm or 47mm = 1.85mm conversion internet)
•H (eyepice Ø) = 1.60 inch or 41mm

If i compared it to a Leupold VX-3 3.5-10x40mm (#66090-66125)
Specifications •G (objectif Ø) = 1.80 inch or (±45.72mm) conversion internet
•H (eyepice Ø) = 1.60 inch or (±40.64mm) conversion internet

Leupold Vx-3 accepte alumina flip cap lens.

I would think about the Leupold Alumina Flip-Back Lens cover-40mm standard & EP (#62990)

Redfeild 3-9x40 are compatible with alumina accesorie.

''If you are thinking of lens protection, the ocular and objective bells are threaded to make them compatible with Leupold’s Alumina and other accessories''
