The thread about the USMC battalion experimenting with suppressors got me thinking.
What are the differences, if any, in accuracy between say a 10" barrel 5.56mm AR-15 style rifle with a 6" suppressor on it, and a 16" barrel 5.56mm AR-15 style rifle?
I'd always heard that barrel length (and therefore increased velocity?) was the important factor in AR-15 accuracy, but then gone on to have that debunked. . I.E. "they say", don't get a 10.5" barrel and expect it to shoot as far, as accurately as a 16" barrel on the same weapon. Is this true?
Can a suppressor replace some barrel length when going shorter? Is it the velocity that matters most? Does the suppressor's increased velocity (I think) take the place of a couple inches of barrel, or is it not enough?
