Will this scope hold up to a barrett m82a1 if so what height on rings — 1 Answer

Yes, it will. All of our optics are built with the same durability in mind. All of our optics are impacted to over 1250 Spike G's. We run the same inspection and checklist on ALL of our optics to ensure they all stand up to the Nightforce name. The ring height you would want is 1.5" on this setup. However, on that gun, the rail already has 27 MOA of taper and this optic has limited dialing adjustment (55 MOA) so you would potentially have to zero past 100yds as the general rule of thumb is to not exceed half of the overal travel if you want to zero at 100yds and this setup would put you extremely close to that.
