M855A1 - 14.5” barrel vs. 20” barrel.
This video compares the performance of the M855A1 ammunition when fired from two different barrel lengths: a 14.5-inch barrel and a 20-inch barrel. The creator addresses comments from a previous video that suggested an 18-inch barrel might have reduced velocities, aiming to prove that barrel length, within these parameters, does not negatively impact the M855A1's performance. The focus is on ballistic data and factual comparison between the two barrel configurations.
