It depends so much on actual use
If we are talking a actual milspec M4 vs A2
Milspec meaning a colt/FN or what ever gov contracted manufacture is pumping out $400-$600 guns for USGI I and over all use would be “combat” give me the M4
Now for a accuracy stand point I see little gain out side slow fire prone with sling where added sight radius will net you “better accuracy”
Now for looks
The M4 with the old cheese grater quad rails .....toss those and put on a decent round or basic plastic guard.
This is also applying that ammo will be of the M195 M855 variety .
I see very little ballistic advantage with the A2 vs M4
IIRC theres about a 225fps swing with M855 20" vs 1 4.5" barrel. Which is about a difference of 30" drop at 600 yards with a 50 yard zero.
