Hello All, first post here but Iﾂ致e got some questions regarding a Gun build
i have a 20 year old or so savage 110 7mm rem mag I got from my dad and Iﾂ知 working on upgrading/building off of it

i bought a bell and Carlson spotter stock for it and Iﾂ知 trying to figure out what barrel I need, I am currently looking at McGowan barrels and their different options leave me with questions.

How do I know what threading my action is looks like the options are savage standard/large/target.?

Also what barrel contour will fit the bell and Carlson sporter stock? Iﾂ知 guessing the savage sporter will fit, but will the savage magnum fit?

I am also looking g to put a break or suppressor on the barrel is there a more common muzzle threading that is normally used it looks like the options are 1/2, 9/16, or 5/8 is there one that is more standard or gives me more options.

Thanks
