INSTALLATION GUIDE & SHIM SELECTION

Rear Spare Magazine Carrier (RSMC) for Meta Tactical MX-1 — installation overview and magazine shim reference.

INSTALLATION IN 3 STEPS

STEP 01
SELECT THE CORRECT SHIM
Use the compatibility guide below to identify the correct shim number for your magazine.

Position the shim with its locking tab facing upward and slide it into the carrier’s internal rail until it clicks securely into place.

STEP 02
MOUNT THE CARRIER
Select the RSMC version matching your MX-1 stock or stabilizer mounting configuration.

Align the carrier with the designated mounting points and secure it using the two installation screws and nuts. Tighten securely without over-tightening.

STEP 03
INSERT & REMOVE

Insert:
Push the compatible magazine into the carrier until it locks securely.

Remove:
Operate the release tab and pull the magazine straight out.


IMPORTANT – MX-1 MOUNTING:

Verify whether your MX-1 stock or stabilizer uses the 2-hole or 4-hole mounting configuration and select the corresponding carrier version. The EVO-specific cheek rest mounting arrangement should not be assumed to apply to the MX-1.
