Mechanically they are one of the two most solid scopes lines made. The other being Nightforce. They work.
Have had dozens of SWFA's on the range, on hunting rifles and at work. The fixed powers optically are similar to Leupold VX2. The 3-9x42mm is closer to VX3 and the 5-20x HD model has fantastic resolution and color rendition and is very, very bright. .
Having said that, "glass" is the least important feature of a scope as they are aiming devices, not bird watching devices, and for what matters in a scope, they are at the top of the heap.
