Muy bueno compadre!!!! Makes it alot easier to shoot at a distance. I have to have scopes on mine cause of advanced glaucoma. Can't see anything withthe iron sights now. Can't even see the sights actually.
Got a couple of Simmons 3X9X40 scopes on my .300 B.O. hand built on a matched Anderson upper/lower and a beater D.P.M.S. in 5.56. Both were very low on the guns and hard to pickup quickly. So, I tried a riser on the .300 B.O. That helped alot. Gonna get a riser for the DPMS. also.
Got a similar scope on an old Colt AR SP1 A1. It is a 3X9X50. Mounted ont he carry handle, it's a bit too high. But, it works.
Yeah, some pics and a range report of your rifle/scope combo would be nice.
