There would not be all the variations that make collecting them fun, that is for certain and when you make dozens of variations of the same gun there is a better chance you get people to buy more then if they only made one model.
But, it would be interesting to compare say all the Ruger #1s to say all of the Colt AR-15s made and compare the production numbers. And it is easier to mass produce the Colt AR-15 then the Ruger #1 and the AR-15 is cheaper too.
Now, yea, the SR-556 model they ave now is more expensive but remember you are not comparing apples to apples anymore then comparing your Ruger #1 to my T/C Contender which is also a capable single shot :wink:
I personally wish Ruger would start shipping the SR-556 as I really want to get one and give it a try and I have a safe full of other AR-15s and really have no need for "just another AR-15" but this is not "just another AR-15" and I want one (or two :lol: ).
