I use an EABCO rear aperture on my CVA Accura V2. I really like it. I also had to install a Williams fire sight front sight as it is quite a bit lower than the CVA factory sight. I killed my Co. cow at 142 yards with my home cast and powder coated Lee REAL 320 gr. bullets. They shoot awesome out of my rifle when combined with Blackhorn 209 powder.
I had 2 tags and was able to take her calf at 184 yards.
My good buddy was also able to hang his tag on a real nice 6 point. He shoots an Accura with a SeeAll open sight and 300 gr. Thor's.
It was a very Hot, dry, dusty and tough hunt but we were able to fill out. Public land DYI hunt. 2 of the tags came off the leftover list.
Happy Hunting to you all,
