Congrats on the Guide Gun. I've wanted a 45/70 for about 30 years, and finally got one about three months ago. I put a Williams peep rear and Firesight front bead on it, and I'm getting groups about 3" at 50 yards. Works for me. I don't need it, but the local hogs are going to get a suprise this year. It's a light, easy to carry powerhouse - just the thing for crawling thru the palmettos in the mud after hogs. Even though my old eyes could do better with a scope, I can center the peep instantly, and shots over 50 yards are rare. I love it!
