rails
I do not have a pic of the Fulton rail, but am familiar with the rail offered at one time by the CMP, and they are one in the same. I think of the maker of said rail, other rail is "Omega", it most definitely not Ultimak. I have an Ultimak on another make rifle BTW. (AK clone)
There are a few differences in the Ultimak and the Omega. . One is the nature of the attachment system. Which is better between the two may be a toss up. the Omega has more screws, and seems a bit more complex. Both seem pretty stable and sturdy. The Omega has some threaded holes on the body that allow the attachment of Pic/Weaver rails to mount accessories, the Ultimak does not.The Omega sets a bit higher off the barrel, and scopes/optics, , even with low rings, tend to end up a tad higher than the same arrangement on the Ultimak.
I bought both my Omega/CMP, and the Ultimak on the other rifle, used, at good prices. In use, I don't see, much practical difference in the two.
Scoping a Garand seems travesty, until one can't mange the peep sight like you'd like........then adding a scout scope seems not so bad.
