This video reviews the Guard Dog Level 3+ Personal Ballistic Shield, detailing its construction materials (aluminum oxide and UHMWPE) and NIJ RF2 rating. The presenter verifies its dimensions and tests its actual weight, finding it lighter than advertised. The shield is noted for its waterproof polyurea coating and its utility in providing enhanced safety during shooting activities.

This video explains the significant price variations in Level 4 armor plates by detailing the impact of different materials used in their construction. It highlights that the ceramic strike face can be made from materials like aluminum oxide, silica, or boron carbide, with boron carbide being the hardest and allowing for thinner, higher-performing plates at a greater cost. Similarly, the backing material, commonly pressed Kevlar, can also be fiberglass, Kevlar, or UHMWPE, each with distinct performance characteristics and price points, with variations even within UHMWPE affecting affordability and performance.

This video provides an in-depth test of Premier Body Armor's FORTIS line of affordable body armor plates. The reviewer, Magic Prepper, tests three different plates (FORTIS 3+ RF1, FORTIS 3+ GT RF2, and Level 4 RF3) against various rifle calibers including M193, M855, and 308 M80. The testing focuses on penetration, backface deformation, and overall performance relative to NIJ standards and manufacturer claims, offering insights into the value proposition of budget-friendly ballistic protection.

This video discusses variations in ceramic body armor, highlighting differences in backer materials and ceramic strike faces. It explains that cheaper plates may require thicker ceramic for stopping capability, leading to increased weight and thickness. Different ceramic types, such as aluminum oxide and boron carbide, offer varying hardness and performance.
