They appear to still be in business via their website: Ironsight
A few years ago I had them refurbish an old Redfield 3x-9x & it came back in great shape & super clear. My only complaint was the lead time - it took them 18 months to turn around. They warned me up front that it may be 6 to 8 months. The cost back then was $85.
Yes they are I talked to them yesterday! If you need one gone thru it 8 to 10 months. But prices are going up and she said get it in before they change web price list and they will honor the 95 dollar price!
