I just put a Nikon Monarch 6-20x 44MM on my Remington 223. wow wow wow
What a great clear crisp scope that sites in fast... Ilike it better than my Bushnell Elite that seems to have an elusive eye set, it takes me a while to find it and that is NOT fun... the Nikon is right there. I would recommend the Nikon Monarch and do as I did: Instead of paying over $400 at a retail store or even online store, I bought a used one for $300 and it is JUST as good as brand new except I don't feel fleeced... so I'm smiling even more when I shoot it... The 223 is a fun fun fun gun to shoot. I hope you enjoy your Tikka and much as I enjoy my Remington... I have heard great things about your model Tikka... and I may get one or a savage next.
