Hi Chaps

My 80 project continues and the metalwork is stripped ready for a reblue.

It's a 1991 Hw80k with the grooves for front sites. I was planning on getting it re-crowned and half unf thread added so I can use the HW silencer I have on my hw100, but it got me thinking...

Is the barrel choked and if so would I lose that if the unf thread and re-crowned work was done?

The price for the unf and re-crown nearly equals that of a new slimtech so there is an argument to just get one of those but I do have a lot of confidence in the new HW mods and this will be a hunting tool.

But if the work will affect the choke, if there is one, then it's a no-brainer.

Any advice would be much appreciated.

All the best
Rob
