I suppose it could have been in the gunshop a while but they do seem to have a reasonable turn over to suspect it being quite recent.
Anyhow the breach required countersinking to remove slight burrs....muzzle was ok.
Seal a bit too low for my liking, with barely 0.2 mm of land between it and the breach face ....which has caused galling on some early ones....it was clear but only for so long i would think.
The paint Job looks like paint compared to the Blued finish on the older 604
The power is miserable....we checked his at 330 fps...
As i guessed he wants me to look at that.
I can usually tweak them to 380 fps and produce a nice clean breach entry... machine shop job, with a shimmed O ring
Set the barrel to correct gap if you need it but i wouldnt bother without the service .
