Tapco TAP22091 AR-15 Magazine Coupler 5.56/.223 Black Aluminum

The Tapco TAP22091 Magazine Coupler transforms standard AR-15 magazines into a dual-magazine system for faster reloads during high-volume shooting. This black aluminum coupler securely joins two 5.56x45mm/.223 Remington magazines at opposing angles, reducing reload time from 3-4 seconds to under one second with proper technique.

What Makes This Different

Unlike plastic couplers that can crack under stress, the TAP22091 uses machined aluminum construction with steel hardware for long-term durability. The opposing magazine design maintains proper balance while keeping the overall profile compact enough for prone shooting positions. Heat-treated aluminum withstands temperatures from -40°F to 160°F without warping or losing retention strength.

Key Features

• Machined aluminum construction with corrosion-resistant black finish
• Compatible with standard AR-15/M16 magazines (STANAG 4179)
• Opposing magazine configuration for balanced weight distribution
• Steel mounting hardware rated for 500+ coupling cycles
• Low-profile design allows prone shooting and tight storage
• Works with 20-round and 30-round capacity magazines
• Tool-free installation and removal system

Field testing shows the TAP22091 maintains secure magazine retention through 1,000+ round count sessions without loosening. The aluminum construction dissipates heat better than polymer alternatives, preventing warping during sustained fire exercises. Competition shooters report consistent sub-second reload times after minimal practice, while tactical applications benefit from the reduced fumbling associated with separate magazine handling.
