In all my years of working/teaching/attending sniper classes, have never seen anyone with a NF optic. Do you know who that was doing the test? In addition, NF optics is the only company that would not send test samples for evaluation. Spoke to their VP when he asked how the optics would be tested. Explained the square test, return to zero test, and field applications using click adjustment for real world work. Never heard from them again. I don't understand this as I would want my optic tested against the best optics in the world with side by side comparisons using the exact same tests.
I agree with RR on the click adjustment and return to zero matter for long range work. However, for the avg. hunter this is not something they need. In testing all the optics through a square test for true click adjustment and return to zero, only 4 scopes could pass it. M4 and VX III 30mm LR Leupold, Schmidt & Bender, and a military 10x optic from Bushnell made for a contract.
However, again for the average hunter not shooting PD's at long range, only holding a zero is key. Only scopes with true click adjustment can be run on a square test anyway. Friction adjustment have a hard time with anything.
As in the brightness control I mentioned in my other post using coatings, it appears using a scope for a hammer is another gimick used for sale promotion. It is not that the other scopes can't do it. It is because use does not demand it. Schmidt & Bender is a steel tube optic and could be used for a hammer as well but don't think you will see anyone trying it that way. Scopes for practical applications need to be as light as possible, stand up to harsh treatment, and be reasonable in price. M4's are for military/LE use and do not need to hammer nails.
As stated by FB, it your choice does the job that is all that matters. Everyone has different needs from their optics.
