B5 Systems Unveils Advanced Modular Platform Stock for 1913 Rail Systems

B5 Systems has introduced an innovative addition to their product lineup with the launch of their new Modular Platform Stock, designed specifically for standard 1913 Picatinny rail configurations. This versatile stock system combines folding capability, adjustable length of pull, and an integrated cheek riser in a single, streamlined package.

Design and Compatibility

The newly released Modular Platform Stock demonstrates universal compatibility with any standard vertical 1913 receiver stock mount rail system. While drawing inspiration from established designs like the ACR and SCAR stock platforms, B5 Systems has engineered a more refined, streamlined profile that reduces bulk without compromising functionality. The stock's sophisticated design language prioritizes both aesthetic appeal and practical performance.

Sling Integration Options

Enhanced versatility comes through multiple sling attachment configurations, including integrated QD sling cups and additional loop mounting points. These Quick Disconnect points feature color-coordinated finishes that seamlessly blend with the stock's overall appearance, maintaining visual cohesion across the platform.
