BALLISTIC INTEGRITY

When combined with the ballistic-resistant armor core, the proprietary open two-piece exoskeleton frame creates a three part assembly that delivers a unique, no-drill-through armor solution maintaining the full structural integrity of the ABS ballistic resistant core. In contrast, many shields with drilled panels require additional specialized hardware to reinforce these weakened areas, resulting in added weight and an increased risk of inconsistent ballistic performance, particularly when subjected to rifle rounds fired at oblique angles. Some manufacturers conduct ballistic testing prior to drilling, making them unable to provide users with NIJ or ASTM compliant data that accounts for "bolt hit" performance.

 

The armor core is coated with a tough Line-X finish that resists dents, corrosion, abrasions, chemicals, and moisture. It is further protected by a moisture-repelling armor jacket made of CORDURA® and Squadron® brand nylon, offering exceptional resistance to UV exposure, tearing, and abrasion. Additionally, the frame system's external perimeter compression straps are strategically placed near the radiused corners to help minimize the potential for damage from hard impacts. Our top priority is making sure your armor performs at its best when it matters most.

MINIMIZING UPPER EXTREMITY FRACTURE RISK

In a recent study published by the ASME Journal of Biomechanical Engineering (Injury Risk Functions for the Midsized Male Wrist and Elbow as a Result of Behind Shield Blunt Trauma) lead by Biomechanical Engineer, Dr. J.E. de Lange (M.A.Sc., Ph.D., P.Eng.). Data was collected to develop injury thresholds using post-mortem human limbs, under loading conditions similar to those recorded in a previous live-fire ballistic shield study. BABT (Behind Armor Blunt Trauma) results indicate the forearm is most susceptible to injury. "The significantly lower forearm fracture threshold in comparison to the wrist and elbow under similar loading conditions indicates it may be the most vulnerable location for injury resulting from behind shield blunt trauma."

 

This study also notes, "It is important that ballistic shields protect users from both projectile penetration and injuries resulting from behind shield blunt trauma. Currently used shields that pass standards regulations on projectile penetration may not be adequate in minimizing upper extremity fracture risk. Results from this study can be used to develop a new standard to assess whether or not shields are adequate at minimizing upper extremity fractures, providing important protection for armed forces."

 

Following personal discussions with Dr. de Lange and guided by the findings and recommendations of this study, Boydd Products independently conducted a quantification of backface deformation (BFD) on the ABS at the forearm contact point, with the frame and trauma-attenuation measures in place. To ensure rigorous evaluation, the 7.62x51mm round (selected for its higher energy output and greater deformation potential compared to the lower-caliber RF1 and RF2 threats) was used for BFD testing at the velocity specified by NIJ and ASTM Standards. BFD testing was conducted by Oregon Ballistic Laboratories, an NIJ approved ballistic lab accredited by NVLAP, and resulted in forearm point-of-contact deformation of less than 2mm, nearly immeasurable for both RF1 and RF2 configurations. Well below the NIJ 44mm threshold set for torso worn body armor. The ABS is built to minimize fracture risk and keep you in the fight. 

 

HANDLING

The patent-pending rigid external frame system is engineered to replicate the firm feel, handling, and control characteristics of traditional shields with bolted handles and forearm straps. In this design, all hardware and accessories are mounted directly to the external frame panels, rather than the armor core or its non-weight bearing fabric color jacket ensuring superior durability and stability.  An external perimeter compression system securely supports the armor in place from all directions, effectively eliminating the sagging, shifting, or drooping common in many fabric-based support or enclosure systems. The rear frame has been designed to provide a limited amount of flex to accommodate the effects of associated BFD.  

​

With its rear frame equipped with the padded forearm brace, high-impact trauma-attenuating forearm pad, and fixed rigid carry handle, the unified 3 piece ABS assembly becomes an extension of the user - enhancing comfort, control, and overall operational performance.
