KRISS USA Inc 9MM Magazine Extension For Kriss VECTOR MagEx 40rd Extension Kit for Glock 17 Magazine Flat Dark Earth KVA-MX2K90FD00 UPC 811607032970

Product Description

The KRISS USA MagEx2 9mm Magazine Extension Kit in Flat Dark Earth (KVA-MX2K90FD00) is a high-capacity magazine conversion platform engineered to expand factory 17-round Glock 17 9mm magazines into a massive 40-round extended stick magazine. Purpose-built for the KRISS Vector 9mm carbine, SBR, and SDP pistol platforms, this conversion kit provides maximum firepower for PCC competition, tactical drills, and high-volume range sessions.

Molded from durable, high-impact composite polymers and finished in a matching Flat Dark Earth (FDE) colorway, the MagEx2 extension outer sleeve seamlessly integrates with the lower receiver contours of FDE KRISS Vector models. The kit includes the extended lower housing, sleeve extension, outer retaining cap, and an extra-long high-tensile steel power spring designed to maintain uniform upward follower pressure through all 40 rounds.

Compatible with factory OEM Glock 17 9mm magazines, the KVA-MX2K90FD00 delivers smooth, drop-free operation, positive bolt catch lock-back on empty, and non-stop feeding reliability for hard-use 9mm Pistol Caliber Carbines.

Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Designed to convert factory OEM Glock 17 9mm 17-round magazines into 40-round extended capacity magazines for KRISS Vector 9mm platforms, Glock 17 pistols, and 9mm AR-PCCs taking Glock mags. (Not compatible with aftermarket non-OEM magazines or Glock 19/26 shorter mag bodies).

1. Perform a complete firearm safety check: drop the magazine, lock the bolt/slide rearward, and visually inspect the chamber to verify zero live rounds are present.
2. Depress the side insert tabs or floorplate retaining pin on a factory Glock 17 magazine to remove the stock floorplate, insert plate, and factory spring.
3. Thoroughly clean all factory grease and carbon build-up from the interior polymer walls of the Glock 17 magazine tube.
4. Insert the extended KRISS extra-long power spring into the magazine body, ensuring correct top-follower orientation.
5. Slide the MagEx2 FDE extension body onto the magazine body rails until the locking bottom cap snaps securely into position.
6. Load magazine to full 40-round capacity and manually cycle dummy rounds to confirm feed geometry and bolt lock-back function.
