We have a Weaver T36, thin crosshair, that gets use on a Colt AR, a No1V in 223Rem and some 22LRs
Easily sees bullet holes at 100 yds and have not tried it a 200 or more yet.
Often called a poor persons F Class glass.
Also doubles as a spotter for 380ACP at 50-100yds.
Weaver said it will handle 375H&H recoil levels.
LaserLyte MBS makes for quick sighting in work.
