Since my GSR is slated to be a "bug-out rifle" I want to keep it as light as possible. I just investigated the weight differences between the pictured Trijicon and Leupold's excellent "2.5x Scout" scope.
Leupold = 7.5 oz
Trijicon = 14.4 oz
The Leupold will only require lightweight quick-detach rings.
The Trijicon will require a rear-facing cantilever rail (to correct the eye relief issue) and rings.
The Trijicon is already 6.9 oz heavier, and the rail/mount will probably add another 6-8ozs (as an example, LaRue's products are HEAVY).
As a result of these facts, I think this rifle is going to get a Leupold 2.5x IER Scout Scope!
