I've got their 3-9x42 with the MIL-Quad reticle. I like it a lot. The reticle is unique but it grows on me every time I use it. The turrets are excellent with no repeatability issues.
The SS line is very underrated IMO. For the money they are the best scope on the market. Excluding cost their upper end scopes are still near the top IMO. They make very tough, very durable scopes with excellent turrets. Their glass is good and the upper end models have excellent glass. They don't have a lot of frills, zero stops, etc., but they flat out perform especially for the price.
Rumor is they have a couple new scopes coming out this year to fit the niche between their 3-9 and their 5-20. I am giddy!
