Modular ballistic wall
View Patent ↗A modular ballistic wall is disclosed for use in shoot houses and the like. The modular ballistic wall can be formed from metal plates having key-holes formed therein which are held together by facing and backing strips. Additionally, the modular ballistic wall is preferably formed so that the bolts used to hold the facing and backing strips to the metal plates do not directly secure a bullet containment frame to the facing and/or backing strips, to thereby prevent damage to the bullet containment frame from weakening the joint formed by the metal plates and the facing and backing strips.
