here is the problem mike ., im not sure if this is do to  something being a kit , or if   completed production gun .
 But I have seen CVA  mountain rifle barrels as small as 7/8 .
 Now was this do to the barrels finishing  or  was that the barrel size . Or  could the case be that a barrel was replaced  and that replacement barrel was slightly under dimension 

 Who can say . We are basically talking about 1/16th . that’s 1/32 difference in either side .
 I found long ago , when it came to CVA  you just don’t know .
 Just last weekend I worked on a fellas  CVA Kentucky . I  have known the fella for a very long time . But actually had not seen the rifle for some years . He was having a problem with the lock holding at full cock .
 So  we left the line and I   broke the lock down and touched up the sear and tumbler . We went back to the line . The last shot is an oxygen cylinder at 235 yards . When he shot  the target rang very  nice . 
 I made a comment that  I have never heard a 45 cal  ring that target so well  and ask what his load was .
 His reply was that the rifle was a 50  not a 45 .
 So I came home and  looked through my old catalogs . I show no listing for 50 cal option in the CVA Kentucky . So I called him up to double check . The barrel is marked Connecticut Valley Arms Kentucky , 50 cal . He said his wife had bought it for him in 1974 new .
So now next month  im going to take my micrometer and  Mic the barrel .and add that data to my CVA info . 
 I don’t think we can assume anything here . . The barrel has to be measured to know   it could very well be the case that Lances barrel is 15/16  but IMO it could just as easy be 7/8
