The MFT Extreme Duty Magazine coupler expands ammunition capacity and makes reloading for speed more efficient by securely joining two magazines for the AR15/M16. It is made of high-impact, superior-grade, lightweight polymer and will not scratch or deform magazines. Easy to assemble two-bolt design will keep your mags in place even through the toughest conditions.
Slimmer mags will require the use of the included wedge (pictured as D). Thicker Mags will not require the wedge.
FEATURES:
• Size of coupler is congruous with all popular magazines.
• Fast and effcient ammunition reloads.
• Two-bolt design secures the magazines in an easy-to-change assembly.
• Advanced yet simple design utilizes ribbing for added strength.
• Easily fits all 5.56x45 Aluminum and Steel Mags, all MFT mags, 30 and 40 rd AR/M4 GEN M2 MOE® and AR/M4 GEN M3™ magazines.
.300 Blackout vs. 5.56 NATO Disclaimer
While .300 AAC Blackout (also known as 300 BLK) and 5.56 NATO cartridges are designed for use in AR-style rifles, they are not interchangeable and must never be confused or cross-loaded. Firing a .300 Blackout round in a 5.56 NATO chamber can result in catastrophic failure, as the larger diameter of the .300 BLK bullet may not fit properly in the 5.56 barrel—leading to a barrel obstruction and potentially serious injury or damage.
Though both cartridges can be used with similar bolt carrier groups and magazines, it is critical that shooters take extreme care when switching between calibers, especially when using rifles with interchangeable uppers or multi-caliber setups.
Always verify the ammunition you are loading matches the markings on your barrel and upper receiver. Mixing up .300 Blackout and 5.56 NATO can lead to dangerous malfunctions, injury, or death. When in doubt, double-check.
