Iron sights? Outstanding job! Very few hunters will ever get an opportunity to take such an outstanding trophy and you did it with iron sights!
I salute you sir!

Thank you Erik, I really appreciate it. Yes, if you look closely it is an AR-10BA2, with match Iron sights. I started hunting years ago with irons, went to scopes, and then back to irons. Same with a bow. I started with a recurve, went to compound uber bows, and now am back to a longbow with cedar shafts. Maybe next I will try a spear..
The best part is I don't have to drive anywhere to go hunt, and there is at least one more that is as big, and another large 3x3 as well. Of course you have to climb a very steep 600 foot incline to get up there..

This one was actually behind my porch at 40 meters about 3 weeks ago, but I had to go on a trip so I could not do it. Besides, that would not have been as sporting..

I have never had a mount done, but I believe this may be one to get done.
