Installation Guide
INSTALLATION GUIDE
REAR SPARE MAGAZINE CARRIER
FOR META TACTICAL MX-1 & MCK EVO
The RSMC mounts directly to the stock or stabilizer arm and provides secure, rapid access to a backup magazine.
BEFORE YOU BEGIN
Confirm that the package contains: 1 RSMC carrier body, 8 numbered sizing shims, 3 M3 screws, 3 M3 nuts and 1 Allen key. Two screws and nuts are used for installation; one screw and nut are included as spares.
01
SELECT THE CORRECT SHIM
Use the compatibility list to identify the correct numbered shim for your magazine. Hold the carrier with the larger insertion opening facing you, position the shim with its locking tab facing upward, and slide it into the internal rail until it snaps securely into place and sits flush with the front of the carrier.
02
MOUNT THE CARRIER
Align the RSMC with two available mounting holes on the MX-1 or MCK EVO stock or stabilizer arm. The large magazine insertion opening must face downward, with the magazine oriented toward the front of the system. Insert two M3 screws through the aligned holes, position the M3 nuts in the opposite-side slots, and tighten using the included Allen key. Do not over-tighten.
03
INSERT THE MAGAZINE
Align the magazine with the bottom opening of the carrier. Ensure the magazine locking tab faces upward, then push the magazine straight into the carrier until it locks securely in place.
04
REMOVE THE MAGAZINE
Apply slight downward pressure to the magazine release mechanism or tab, then pull the magazine straight out of the carrier in one smooth motion.
INSTALLATION NOTEIf a cheek rest is already installed, use the two remaining available alignment holes. Always confirm that the carrier and magazine are securely retained before use.
