Back to work on the ole lefever

I have the barrel and top lever fit (I think)and wanted to take it out for a few shots before pr0ceeding with other work.

I am seeing something that concerns me.

When I have the barrel on the receiver and minus the forearm metal, with good thumb pressure on the front pushing it into the barrel I see no light and cannot get a .0015 gauge to even get started anywhere around the barrel/breach interface. This the same whether I have to top lever engage or not.

Ok now when I put the forearm metal on. the metal snaps down pretty tight and I can tell it tensions the whole set up and although not bad does tighten up the opening/closing of the assembly. The thing that concerns me is that this opens up a gap on the left barrel face and I can now barely slide a .003 gauge in the gap as well as see light evenly around the whole barrel face surface. this is only on the left barrel.

When I take the forearm metal off I cannot feel any lateral movement between the barrel and receiver when closed and just a bit when opened.


What say ye?
The gun is looking good though so I have that going for me.
