So, basically my question is this:

I've read some stuff about the receivers not being identical and hence the barrels of the 16s/17s not being swapable. I'd really like to find out a clear answer to this.
1) Would a stock 16s 5.56 barrel assembly fit on a 17s?
2) Are the 17s and 16s lowers swapable?
3) Are the bolt carriers between the two swapable?
If not, does the conversion of a 17s to 5.56 require totally different parts?

Thanks all!

The 17 receiver, bolt carrier, and lower are longer to accommodate the larger 7.62 round.

Yes different parts
