All I use are Nikon scopes, on my CZ 22LR, Bushmaster AR, and my Remington 700 LTR. I also have an older pair of Nikon compact binoculars that have never failed me in almost 20 years -- no problems whatsoever, through hiking and on the range.
The 700 LTR wears a Monarch 3 4-16x42 mil dot with side focus. It is crisp and clear, under $500, and I chose it after looking for weeks through Leupold, Bushnell, Vortex, Burris, Zeiss and others. Good enough to put 10 rounds into less than half an inch at 100 yards with my handloads. Read Nikon reviews on Optics Planet and elsewhere.
I give the Monarch 3 two thumbs up.
