The Level 3A 9MM Ballistic Elbow Guard allows the wearer to customize ballistic protection based on the mission. Each Ballistic Elbow Guard comes with two removable ballistic inserts and one foam pad. Two ballistic inserts stop a Level 3A 9mm pistol bullet moving at 1,446 Feet Per Second/ 441 Meters Per Second. One ballistic insert stops a Level 2A 9mm pistol bullet moving at 1,066 Feet Per Second/ 325 Meters Per Second. United States National Institute of Justice standard 0108.01. One insert also provides Military Standard 662F V50 penetration resistance to .17 caliber fragments moving at 1,343 Feet Per Second/ 409 Meters Per Second. Invented by a veteran of the US Army Ranger Regiment and Special Forces. The wearer can customize the pad by either removing the ballistic insert or foam pad based on the mission. If the carrier wears out, purchase the less expensive non-ballistic Tactical Elbow Guard. Simply take your original ballistic inserts and place them inside your new carriers. If you are going to need multiple camouflage options, purchase the Tactical Elbow Guards in the other colors needed along with your original set of Ballistic Elbow Guards. Patented. Purchase the Ballistic Knee Guard for additional protection.
