Mackay, what was the red dot sight in your early picture? Will it hold up to 270gr, 900fps loads?
Thanks.

Frank,
That is a Burris Fastfire.
Yes it will handle the 270 grain, 900 FPS loads fine, as I have been using it for T&E purposes for a while now, and have had zero issues.
That said, if I was looking to purchase one today, I would opt for a Holosun or Trijicon RMR, both of which have good track record on guns that see a lot of use.
