Welcome aboard.
I have 3 of the Buckmasters, Side Focus with Mil Dots. I'm very pleased with them. One is on a 6,5x68 AI and it's a snorter, the other two are on varmint rifles.
They do everything I expect of them. They are clear and repeatable. I looked at the other two scopes you mentioned and chose the Nikon because of the extra power. I sampled them outside the Store and the Nikon was my favorite.
The other 2 were good also and I wouldn't turn them down. They just didn't meet my needs.
Sides that the Nikons were on sale, that may have changed my perspective somewhat.
Best wishes, Bill
If you decide on the Buckmaster get the one with the Mil Dots not the one with the BDC. The BDC might be OK for BIG Game but they aren't worth a hoot for Varmint or Target work. Words from the wise.
