On the fence between a Nightforce NX8 4-32X50 and a Vortex razor hd 4.5-27x56. I've had lots of (positive) experience with Vortex but have yet to own a NF, this is going on my new .308 build. Leaning towards the NF after handling them both in person but I just can't get over the warranty Vortex provides, whereas NF only covers manufacture defects etc. Id like to hear your first hand positive and negative experiences with both!
