Barrel thread question

[x_wolf]

Can any one help me with following problem?
I can buy from a friend used Marlin XS7 in 308W. I also have used varmint barrel 243W from Howa 1500 (which I want put in the Marlin...). Is it the same barrel thread on this two rifles or is it something totally different?
Thanks for any advice.

Not the same and not worth the $ to do unless you can thread and chamber it yourself .
Rarely can barrels be changed withing same make , model and headspace and index properly . Excluding those that use barrel nuts .

I just noticed your in Slovakia , I'm not sure of the barrels available , so it may pay to have a smith rethread and rechamber .
