They are great people to work with.I bought a used NF once that was missing a lens cover. I called NF and told them I wanted to buy one but didn’t see any parts listed on their website. They sent me one for free. You might try calling them.
i to had a screw in lens cap damaged and called to buy one - they sent me one on the house- i bet alot of rifle ranges have alot of them people have leftJust purchased a used (like new) Nightforce 12x42 Benchrest scope which came without the screw on turret covers. Checking to see if anyone has an extra set, I realize this is a long shot!
Thanks much!
