The Tactical Solutions version can now be had for $499 post paid and I wish I had waited a few months till this happened. Thats $100 under what I paid.
I submit: the competition in the AR 22LR arena is forcing some of the top end makers of options to lower prices. I think if you are in the hunt for a 22LR shooting AR , a bit of waiting will allow you a better menu of options and savings.
At my age: I just felt I could not wait but actually, thats a poor excuse.
