Glad to hear that you like it. My father-in-law likes his a well.

I just got my new .458 caliber upper for my AR-15. Similar ballistics to your .45-70, but in a gas operated semi-automatic configuration. The sight is a red-dot scope with no magnification. Shoots nice tight groups.


Here is a .45-70, .458 SOCOM, .223, and a .44 Mag for comparison.


And how they fill out a magazine.


A 10 round AR mag hold 4 .458 rounds, and a 20 rounder holds 6.
