Notable features on this new magazine design include a new feed-lip design that's been patented by the company, as well as magazine bodies with embossed texturing, a newly developed anti-tilt follower and built-in caliber markings for easy identification.
The SureFeed E2 AR-15 magazine is designed to enhance reliability, thanks to new, low-friction feed-lip geometry that minimizes the amount of force needed for the bolt to strip a fresh cartridge from the magazine. Added benefits are also seen in real-world environments thanks to this new design, since it provides consistent reliability even when fouled by dirt, dust or carbon fouling.
Found on the sides of the magazine body are embossed texture patterns, the first of their kind seen on a metal magazine body. This new texture pattern provides a secure grip for magazine changes or other maneuvers, particularly in damp environments or for users with gloved hands. Despite the aggressive new texture, the pattern is designed to not interfere with the insertion or removal of magazines from chest rigs or other pouch-storage products. Another added feature found on the magazine body is an embossed "5.56mm" marking that allows for instantaneous, visual caliber identification before loading.
Completely made in the USA, Surefeed E2 AR-15 magazines use a magazine body and floor plate made from heat-treated 6061 aluminum for added durability. Inside the body, users will find a self-lubricating, anti-tilt follower held into place with a mil-spec stainless-steel spring. The magazines can be had in the company's mil-spec DFL gray finish or with a PTFE finish available in black or desert tan.
Each SureFeed magazine sold by the company is put through a rigorous quality-control process, testing aspects like feed-lip tolerance, weld integrity and component quality. The SureFeed E2 AR-15 magazine is available in 30-round standard-capacity models selling at a suggested retail price of $19.95.
