For about the same money, you can get one from White Oak Armory (WOA), which will probably be better than you are.

And for just a little more than that, you can get one from Compass Lake Engineering (CLE) or Craddock Precision..................both of which are as good as it gets.

All the above, IMHO, will be more consistently accurate than most Rock River's.............which is not bad, just not in the class of the others.
