Rifle Scopes Older Nightforce NXS 1-4x24mm?

[AKGuide]

I have a discontinued model NXS without zero stop but can loosen one Allen screw to make turret go to zero. I was wondering if anyone had this older model and if they knew the size Allen wrench needed to do this? The night force site is down or something so thought I’d ask here. Thanks in advance

I figured it out. It uses a 1/20” Allen wrench.
