Really depends on what your intended purpose. My first 6.5 Grendel was a 16” set up just like my duty rifle which was a 16 carbine gas length 5.56/223. I currently have four AR-15’s in 6.5 Grendel, 2 sixteen inch, 1 eighteen inch and 1 twenty inch 6.5 Grendel.
The 16” 6.5 Grendel can be used for hunting up to 400 yards depending on bullet/load used. The 16” 6.5 Grendel can be used for rifle matches, CQB and target shooting. I’ve shot my non free floated 16” barrel 6.5 Grendel out to 800 yards. I ran out of elevation and had to use my mildot scope to get on target. My 16” 6.5 Grendel had produced less than 1 MOA groups at 600 yards with factory A-Max. I normally shoot at 450’ ASL and will eventually get a 20 MOA mount for this 16” 6.5 Grendel.
I took some pictures of my 16”, 18” and 20” AR-15 6.5 Grendel AR-15 to show the differences. I also attached a link to chronograph results for 16”; 18”, 20” and 24” AR-15’s in 6.5 Grendel.

Here is a link to a little test I conducted comparing the 6.5 Grendel to the 5.56/223 for self defense.
