Magazine Couplers Guide
MAG|Coupler™ is a floorplate replacement that joins two compatible magazines back-to-back so you can keep them paired for storage, transport, and handling. It does not change magazine capacity or firearm operation. Each magazine keeps its original round-count and function.
Made in the USA • Patented (US Patent No. 10,126,076)
How MAG|Coupler™ works
Floorplate replacement
MAG|Coupler™ replaces the magazine’s existing floorplate to create a secure, stable coupling between two compatible magazines. No permanent modification is required.
Two discrete magazines
Each magazine remains independent. MAG|Coupler™ does not combine capacities and does not change the mechanics or operation of the magazines or the firearm.
Pouch compatible
Designed for practical storage and transport. Coupled magazines are intended to work with standard magazine storage solutions (see pouch options below).
Compatibility matters
MAG|Coupler™ is not universal. Use the product listings to confirm the exact compatible Magpul® magazine model for your platform.
