・This is a speed reload insert kit made by FIRST SPEAR for MP7 (4.6x30mm) magazines. ・This kit includes a "Kydex insert" shaped to fit the corresponding magazine and a "Velcro sheet" for height adjustment, allowing it to be built into the company's multi-mag pouch Rapid Adjust (fs28431) as an additional option. ・By attaching the male side of the Velcro sheet to the inside wall of the insert in a U-shape, you can adjust the insertion depth of the magazine. Attaching it shallowly allows for quick removal, while attaching it deeply increases retention and stabilizes carrying. The insert material is a soft fleece-like fabric, so you don't have to worry about scratching your magazines. #FIRST SPEAR #AirsoftGear
