I had the chance to fondle a USoptics scope on a local Police snipers rifle, a Robar SR90 in 308 win, the rifle had a 18" barrel with an AWC Thundertrap suppressor, very cool setup. The scope was an SN3 1.8-10X44 I think I am in love!!! The glass was the best I have ever seen. The scope was very impressive to say the least and talk about high quality machining. I can't wait for to get mine.
