Just asking would the 3/4 J2.5 weaver clear the safety since it is smaller? I have one on my Model 67 Winchester. My dad originally had it on his 1917 Enfield. The eye piece is less than 1" in diameter and can work with about a 6 inch eye relief. Probably not as bright as some, I did take the lenses out 40 years ago and cleaned them. Did not have any nitrogen to fill the tube so I used propane. Probably left a little petroleum residue on the lenses, but it is not terrible.
