R.R.A.C. Rails mount securely and easily

R.R.A.C. Rails mount very securely utilizing internal clamping blocks actuated at the end of the rail.  No levers or side clamping screws.  Angled dovetail surfaces machined into the clamping blocks force a tight union of rail and tube with superb repeatability.
