The markups vary across the board for optics companies. I work at an archery shop that also has sister stores that carry guns and optics. I get everything at cost. The markup on Nightforce isn't even remotely close to what it is on Vortex and Leupold.As you probably already know, there is tremendous markup on optics. I have a friend on the inside at Vortex and can get me anything they carry for 50% off, so that means there is probably another 25% to play with there. If 10% of their products fail, and they replace them, they still have a large profit margin.
