So I recently purchased a KAC SR 15 Mod 1 and was planning on buying a Vortex 1-4. After being convinced that the extra X2 power is worth it, I have decided to go with a 1-6. I am stuck between SWFA 1-6 and Leupold Mark 6 1-6 Illuminated CMR-W 5.56. The only thing is I have zero experience with either reticles as well as SWFA's glass. I am able to get a pretty good deal on the Mark 6 as well. I was wondering if the Mark 6 was worth paying $500 more instead of the SWFA. If anyone had any experience with both or just one I would appreciate your input. If anyone had any suggestions for a good quick detach mount I would certainly appreciate that as well. Thanks everyone I really appreciate it.
