Great design, look and optical clarity

My first Sig Sauer optic was a Romeo 6T which I took a chance on only because I got it on flash sale from another site for half off MSRP. It was loaded with features and quality, and it hooked me on Sig optics. Fortunately when I started looking at the Romeo 4 series for another rifle I came across Osage County Guns, and picked up a 4S with the Armed Professional Program discount. The 4S has a few less features but same great quality as the 6T, and is more compact which is what I wanted for my other rifle. I have the circle-dot BDC reticle on both optics, and after using a ballistic calculator to determine holdovers, I can easily hit 12” gongs out to 500 yards using the 4 BDC dots in the reticle even with my 50+ year old eyes. Don’t bother with another brand… I tried a few and returned them all, then I found Sig Sauer. I’ll definitely be buying a Sig Juliet 4 or 6 magnifier when Osage has them back in stock (for when I’m shooting paper targets at 100 yards or hunting).

Thank God I found Osage County. Their prices are unbeatable, their costumer service is great and their shipping services is on point. My husband has been looking for this sight for a while but he refuses to pay retail price. I purchased the Romeo 4S sight for his MPX for Valentine's Day! Who would of thought that a sight can make a man so happy.
