I like to name my rifles, especially high walls and this one currently is the ''Not Quite"  
I finally installed the 40-65 barrel that came with the Gun Broker action.  No real problems except the forend screw location was 'not quite' close enough so there is a slight gap between the forend and the action.  The wood does 'not quite' match. The firing pin strike is 'not quite' high enough although it fired just fine. The front sight dovetail adapter was 'not quite' flush with the barrel and finally, the Marbles tang sight is 'not quite' clicking into a positive vertical position.  I know how to handle the forend and pin strike (needs longer link) but will have to research the tang sight.
Oh, also there is 'not quite' a finish on the metal.  

That would assume that I can use iron sights effectively like I did years ago. I have an eye Dr appointment on Monday and will ask about my annoying artifacts when looking through a small aperture.  I will try it out as is or probably with my mid range Heilman sight.  I probably will not keep it as a 40-65 though. I have a nice one already. I need to do some measurements of the flat spring and forend screw locations. If both are 1/16” too far out I need to check headspace. The flat spring hanger I used has the hole slightly forward so maybe the barrel needs to be screwed in 1 turn. That might require a reamer.  The investigation begins after breakfast tomorrow.

You forgot the buttstock is not quite checkered to match the forearm.

" I think it is a modern made forearm with a ‘plastic’ look to it. "

Interesting, so what finish is on it? What is it made of? I'd like to see a close up of the finish and checkering.

The 'Not Quite' is ready to rock and roll.  The forend gap is more like 1/32" and is acceptable.  Some recommend such a gap to prevent any forend/receiver accuracy interference. The pin strike is OK as is IMHO. The flat spring dovetail is in the correct place and the one hanger I put in which moved the screw location in about 1/16" works fine with the flat spring that came with it.  I had to drill out the top tang screw hole which looks to have been welded and a standard (no sight) screw head would not fit.  The is still a gouge on one edge. The head space is about .006 without a case.  I also made a temporary wood insert for the sling swivel cut out so it can be fired off a bag.   
I will see how it shoots as a 40-65 but in the long term oit will most likely be rebarrelled.

Still thinking about the headspace without a case?   

OK Joe, how about barrel to block clearance. It is important of to close with a case that sticks out.  In this rifle case both are fine.

Gee whiz, Jack, give a dog a bone.......
