Handguard lengths

I have a simple question that with the seeming lack of standardization in .308 AR's, may not have a cut and dried simple answer.

Are 5.56/.223 mid length hand guards interchangeable/the same size as .308/7.62  mid length hand guards?

If you are asking about A2 type handguards, yes -15 is compatible with -10 systems.

If you are talking free-float, the barrel nut diameter is somewhat different.

Thanks, I wasn’t clear but, yes, I’m asking about A2 or drop in non free float types.

On my A-2 Armalite AR10 upper Ar-15A2 hand guards fit. Free float or anything after market for AR-10s is another matter. Whoop almost forgot to add that this the early AR10 series that used modified M-14 mags. Don't know if they changed anything on bbl nut size along the way.

My AR10  carbine has 9 inch handguards.  My AR 15 carbine has 7 inch handguards.  I spoke w/ Magpul CS; they said their 9 inch and up MOE handguards will fit.

Ok, so kind of a follow on question:

Are grips like the BCM Gunfighter interchangeable between 7.62 and 5.56 AR platforms?

Also thanks to all who responded above to my original question. It is  much appreciated.
