Just received my sweet .223. Haven't shot it yet, but it looks like a really nice piece for the price, well put together with a solid feel and very clear optics.
A word of caution: you'll see other people complaining that the allen bolts that fasten the interchangeable turrets are easy to strip: this is because the scope ships with an allen key that is slightly too small for the socket. It's a metric problem I think. At any rate I used the allen key out of my Pachmyer set and it fit perfectly and works fine.
The only other flaw I'd note is that the scope comes with screw-in aluminum end caps. These are really nicely machined, but they are fiddly, take awhile to take off, and of course then you have to stick them in your pocket. Would be better to replace them with some quality flip ups in my opinion. On the cosmetic front, BSA should ditch the puffy clear plastic logo on the side of the scope. Looks a lot cheaper than the scope deserves.
I think the scope is an excellent design and well-constructed. If there is any interest I will post a more thorough evaluation after I've shot with it.
