All,
I am in the progress of machining a fireforming bbl for my RPA Quadlite action. The action is new so I don't have an old bbl to work from.
The recoil lug supplied with the action is going to be left off the action as I am preparing a center type lug (like the Barnard actions) so the rifle can have switch bbl capabilities.
Now to my question. The first .500" forward part of the Quadlite recervier ring is not threaded. The illustration supplied with the action shows the bbl tenion about .002" smaller than the action and I assume this diameter is to fit the recoil lug and then slip into the front (non-threaded portion) of the recevier.
Is this non threaded portion of the tenion necessary? Can I just thread the action ala Remington and let the bbl shoulder butt against the front of the action? I don't see why not but this is the first RPA Quadlite I have fitted.
Also, the RPA drawings don't specify a dimension (clearance) between the end of bbl tenion and the face of bolt lugs (total length of the tenion). Most actions I have researched call out .005" for clearance between these two surfaces. Is this acceptable for the RPA Quadlite?
As there is no recess or coned surfaces, I assumed I could use .005" on the RPA as well.
Thanks for your help.
Bob
