I have a 64MP and think it is a fine fine rifle but have grown to love my H&R M12. Heavy sumbitch but the extra weight over my 64 has helped my offhand scores this winter.
There are a few M12s still out there, some with the sights that came on them from the CMP but most do not have sights.
I saw one up for auction on
WWW.Auctionarms.comwith the Redfield sights. Basic auction that was last listed at $499.
Good deal on that IMHO, especially with the sights.
We shoot mini-palma at 200 yards and it is an absolute blast. I wish we shot it more. First time I shot I was amazed that .22s were that accurate at 200 yards. We shoot any sights, you can use a sling or a coat.
I would highly recommend taking a long look at an M12. I'd call it a poor man's Winchester M52. Mine shoots sub MOA with PMC Scoremaster and will shoot even better when fed Eley.
