ya, everyone has their own needs
and like tony's bias towards SEI (which is perfectly okay) , I'll admit to having my own biases towards the casm and other products from that company..... which based on my experiences is perfectly okay as well
in the end , for those wanting to scope the m14, first decide what your own needs are. Some mounts require purchasing additional items to make the scope useable, such as adjustable or fixed cheekrests. Some are low enough to keep the irons as is but ring choices become important so that the rear of the scope doesn't rest on the aperture. In fact, on my arms 18 equipped rifle, wanting the lowest sleekest profile, and lowest scope mounting position possible, and because I did not want to add a cheekrest to my stock, I had to carefully shave the top of the aperture until it cleared the scope. I could have used one size up in ring height , but then I would have required building up the cheekrest area to correspond with the scope height. This also was all custom to my own personal fit to the rifle and scope, so what worked for me, won't necessarily work for everyone.
I also hunt and getting my m14 rifles out in the field, on my shoulder, putting miles on the boots is a whole nuther facet of owning, shooting (killing), maintaining and equipping/accessorizing an M14.
High mounts requiring cheerisers are not a benefit to a hunter in the field, adding weight and giving the rifle a larger profile, making it that much more cumbersome and snaggy on the bushes or getting out of a vehicle ect ect. Having hunted for years and a good many of them with an m14 type rifle, I've got upmost confidence in my ability to shoot both with an optic or soley with irons and have come to value the m14 iron sights as some of the best I've ever used in the field.
if you are building a range rifle though, or a "target rifle" , I don't think it matters much which one you choose as long as it has a solid track record and most importantly, FITS you and your shooting needs. beyond that it's all just opinion and unfortunately, bias
