That could enlarge the rear of my front sight base and thread it to M18x0.5.

I am looking to add a Eagle Eye type lens to my Anschutz 1827, I would remove the base and deliver it along with a sample insert.

I bet you could rip a squirrel a new asshole with that thing.

I can't help you with a machinist but were you the one who was looking for one of those a while back? I'm glad you found one. Oh, and yeah, I'm jealous. Someday.....

Yes that was me. After 3 years of looking, I found one and it was even in our state.

I used it this year for the small bore silhouette league at Danial Boone. We shoot standing at 40, 60, 80 and 100 meters at little friken metal targets. Most shooters use scopes, but I went old school this year and used irons. I was loosing the target in my aperture so I taped (yes, blue painters tape) on a lens from another rifle and it worked (increased my scores 20%)

Drop me a PM I can take a look over a beer.
