When deploying larger-format submachine guns or pistol-caliber carbines—such as the Sig Sauer MPX, CZ Scorpion EVO 3, or H&K MP7—securing supplementary magazines in a low-profile front pouch can be difficult. Standard pistol or narrow SMG sleeves are too tight, causing magazine drag, while traditional covered pouches add unnecessary bulk and slow down reload indexing.

Engineered by USA tactical manufacturer Ferro Concepts, the Turnover™ – Quad SMG Large delivers a purpose-built 4-magazine elastic retention insert. Constructed from heavy-duty military elastic, it provides firm passive friction (Elastic Retention) to hold large-format SMG magazines silently and securely without flaps, bungees, or mechanical hardware. Designed with hook Velcro on the rear face and loop Velcro on the front face, it anchors cleanly inside The Slickster™ plate carrier, the ADAPT Kangaroo Front Flap, and the DOPE Front Flap. The front loop face preserves modular stacking capabilities inside multi-layered front flaps.

Fitment Note: The Large variant is dimensioned specifically for wider SMG magazines such as Sig Sauer MPX, CZ Scorpion EVO 3, and H&K MP7. For narrower magazines (H&K MP5, Glock 9mm extended stick magazines), please select the Turnover™ – Quad SMG Small variant.  

Key Features

• High-Tensile Elastic Passive Retention: Built from heavy-duty military elastic that exerts strong friction to retain magazines through aggressive movements while enabling fast, silent open-top reloads.

• Seamless Carrier Compatibility: Designed around The Slickster™ plate carrier cummerbund flap, and drops directly into the ADAPT Kangaroo Front Flap and DOPE Front Flap.  
• Ultra-Low Profile Footprint: Flat, lightweight form factor adds zero redundant volume to your front plate setup.

FAQ

• Q: What is the difference between the Turnover Quad SMG Large and Small versions?
  • A: The Large version is dimensioned specifically for thicker magazines such as Sig Sauer MPX, CZ Scorpion EVO 3, and H&K MP7. The Small version is sized for narrower stick magazines like the H&K MP5 and Glock 9mm extended mags.  
• Q: Is the Turnover Quad SMG Large compatible with the Ferro Concepts DOPE Front Flap?
  • A: Yes, it is fully compatible. The Turnover series is built to drop directly into the interior hook-and-loop compartment of the DOPE Front Flap and ADAPT Kangaroo Front Flap.
