AR500 Armor VS M855A1 & M193 (14.5, 16 & 18" Barrels)
This video investigates the effectiveness of AR500 steel armor against common rifle ammunition, specifically M855A1 and M193. The core question is about barrel length: will shorter barrels (14.5", 16", 18") still penetrate AR500 steel, or is a 20" barrel required? The video aims to experimentally determine the minimum barrel length needed for these rounds to defeat AR500 armor.
