Backordered. They are not that good IMHO.

Their clearest one is the 10x42. The 16x kinda SUX and 20x REALLY REALLY REALLY SUX!!!

The <$200-$250 (On sale shop smart OR-NOT!) Bushnell TAC front focus 5-15x40AO Mildot is much nicer.

You can choose to spend more for less satisfaction.

The $120 - $130 (MAKE OFFER) Barra H50 2-10x from EBay with questionable Warranty WHOOPS it's butt too.




 
They may not be optically that optimum but mechanically they are super rugged. Some people are just looking for a rugged dependable gun sight first and optical quality second. Needs differ, and the OP didn't specify. I own a 10X SWFA and a Tac Vector fixed 10X and I prefer the TV for the reticle, but the SWFA is obviously way better built. If I was going to start clicking or if I really had to count on durability I would go with the SWFA every time. The brand has been used and abused by operators for quite a while now and has a pretty good record at getting the job done, -especially meritorious when considering the price.
