Requiring only the use of two included Allen wrenches and simple instructions, the Springfield Armory +5 extension is a quick and easy way to increase the capacity of a 5.56 NATO-size Magpul PMAG.
The U.S.-made extension, which weighs 2.5 ozs., is machined from 6061 aluminum billet then hard anodized. It works with the OEM magazine spring, and its two-piece design allows access to the magazine body for cleaning and service.
Available in red or black, the extension comes with a lifetime warranty. MSRP is $40.
