I lost one of the turret cap screws on my first gen ATACR 5-25x56. Was resetting turret to zero at the range and dropped it.
Interwebs searches yielded surprisingly little info. Mostly “call NF”. Seemed like something I should be able to handle. So, I did some measuring. Turns out, on this one and a few older NXS that I have, it’s a simple 8-32 x 3/16” LNG 118deg cone point set screw.
I think they changed designs at some point, as a NXS that I just had the elevation turret replaced on is different. I suspect it’s the new “upgraded” design.
If you’re clumsy like me and lose one, reach out. I have 49 extras. lol.
