Converting a 5.56 to 308
I was wondering is it possible to switch uppers on my ar15 and replace it with a 308? I don’t want to purchase another whole kit but would like to just buy a different caliber upper.

Different lowers completely.

7.62x51 won't work but you can get a 7.62X39 upper for an AR15 lower.

Re: Converting a 5.56 to 308
also 308 AR pattern rifles are not all interchangeable either. the 2 main patterns are the armalite (the AR-10) and dpms (LR-308)

Re: Converting a 5.56 to 308
308 is too long for the AR 15, but you can still change calibers.
as mentioned - 7.62x39
7.62x35 aka .300BLK
I just built a .458Socom. It's competitors would be .450 Bushmaster or the .50 beowulf.
Probably a few more I'm totally clueless about. I don't remember if 6.8 fits AR15?"It seems that the Constitution is more or less guidelines than actual rules"

Re: Converting a 5.56 to 308
Probably will go with 7.62 by 39 as I don't want to reload and it's cheaper than a 300 blackout.
