10.3” vs 11.5” AR barrel long range comparison

Curious how a 10.3" 5.56 AR barrel performs at distance vs an 11.5" barrel? Tune into this video for a look at a real world side by side comparison of these popular short barrels out to 820 yards. We also have some new NAS3 high pressure ammo provided by Phantom Defense that we will work into testing to see how the increased pressure/ velocity will change the performance of barrel length.
