While polymer magazines do have their benefits and space age aesthetic, aluminum mags are not to be forgotten about. One of the benefits that aluminum has over polymer is that it does not swell in extremely high or low temperatures. The aluminum feed lips are also strong enough to withstand the pressure of a fully loaded magazine over long periods of time without bending or breaking.

The history of Okay Industries goes back to WWII where they helped manufacture millions of M1 Carbine magazines for the United States Military. Fast forward and they helped co-develop the 30-round M16 magazine and has been a preferred supplier of magazines to the U.S. government ever since. Now Okay Industries are making their widely popular AR-15 magazines available to the public with the SureFeed and SureFeed E2 designs.

Works perfect, loads easily. Easily my favorite 20 rd mags. Smaller footprint than polymer 20s, and looks better than those retarded curved 20s.

Best AR magazines you can get. Period.

Best 20 round mag you can get for an AR-15! Okay Industries is a Govt./Mil. contractor (cage code 33710), and make mags for Colt's Defense. I have some of these that I used in service 20 years ago, and still function fine. Don't worry about the finish, just be assured they WILL work when you need 'em to...

Compact and reliable


Runs and looks great in my Colt 607-inspired pistol. It's also significantly more compact that most modern 20 round AR mags. Only issue is that the finish wears easily.

The Best AR magazine...

Probably the most reliable and durable magazines available for the AR platform. I still have a few Okay's that I used in service with the 82nd ABN Div. during the 1980's, and they still function perfectly. Trust me, you won't find a better 20rd (or 30rd) AR magazine! And Primary Arms customer service is outstanding!
