This magazine is not compatible with FN Five-seveN or Ruger-5.7 handguns. It is only compatible with 5.7x28mm AR-style firearms.
Wow! You’ve finally built the AR-57 of your dreams! Only one finishing touch remains: that all-important magazine. Better jump on this opportunity to order a BIG 55-round drum magazine by ProMag!
It’s made in the USA. Its DuPont Zytel polymer body and blue steel upper tower give it superior durability and rigidity. Its heat-treated stainless steel spring and injection-molded polymer follower both serve their purposes reliably. Best of all, it holds 55 rounds of the good stuff! Emptying this thing out is like letting loose a huge swarm of extremely angry bees on your target. (Best stock up on 5.7x28mm now if you haven’t already.)
This is a high-capacity magazine. We encourage you to avoid transporting it to or through jurisdictions where it has been made illegal. It would be a very silly thing to get arrested over.
Features and Specifications:
Magazine Capacity: 55
Ammo Caliber: 5.7x28mm
Firearms Platform: AR-15
Quantity: 1
UPC Barcode: 708279016677
