OEM-Style Feel: Maintains familiar ergonomics and consistent press so your muscle memory stays intact.
Great for Builds & Spares: Ideal for new SCT frame builds, routine refreshes, and field-ready spare parts kits.
*Always verify compatibility with your specific model and mag body before installation.
