If it was my company, I would mark them "inside" where it is not visible.

I am the proud owner of ACOG6x48PSA27:1
6x48 for 308 red chevron it is a very nice scope and I just noticed the list price went up 500 bucks from 2k to 2500.
Check out psalm chapter 27 ver 1 psa27:1 on the scope.
I knew they had the scriptures on them when I bought it.
I thought that was pretty cool being a Bible beliveing man.
Not that the goverment models should have it on there that should be up to them. I heard the ones that didn't have the scriptures on them weren't as accurate anyway.

if i remeber correctly, I beleive the founder of Trijicon sterted pttin scripture references on the sights DECADES ago. BEFORE the military contracts. I think I read that on fox news.
As far as the "scripture removal kits" there sending out, I HOPE it consists of a roll of eletrical tape to cover up the scripture.
That worked REAL good for the check engine light in my car. LOL
