Great with holosun 510c - Sig Sauer 4x 24mm Juliet Red Dot Sights Magnifier

Bought instead of Holosun magnifier due to 4x vs 3x mag, better finish, same price ($311 for this with discount). First Sig product for me, very well packages, came with 2x risers, Allen key, and extra lens cover (replacement). OP shipped for free in 5 days and have me a price better than advertised. QD mount is really solid, won't budge, flips easy, clear glass. Eye relief leaves a bit to be desired, I have to push my face up a bit further on the stock but still good. Need to get range time with it, but first impressions are great.
