Overview

Built for ArmaLite AR-10A(R) rifles chambered in .308/7.62mm, this factory-made 20-round magazine is intended for shooters who want the same magazine pattern supplied with new rifles. Its heavy-gauge steel body and contoured follower are described as supporting smooth feeding and helping the magazine hold its shape when fully loaded. The design is specific to AR-10A(R) Type "B" lowers and will not fit other makes, models, or the AR-10 type "A" platform, so compatibility should be verified before purchase. With a black, parkerized finish and factory-marked floorplate, it suits hunting, competition, and law-enforcement use where the correct fit is the priority.

Pros

  • Factory-made Generation II magazine built by ArmaLite
  • Heavy gauge steel body is designed not to distort when fully loaded
  • Contoured follower supports smooth, reliable feeding
  • Available in 5-, 10-, and 15-round capacities
  • Factory marked floorplate included
  • Purpose-built for AR-10A Type B lowers, not converted M14 magazines

Considerations & Trade-offs

  • Fits only ArmaLite AR-10A(R) rifles with Type "B" lowers; it will not work with other makes, models, or the type "A" AR-10 designed for P-MAG magazines.
  • The 20-round capacity offers more rounds on tap, but it also means a larger magazine profile than the 5-, 10-, or 15-round options mentioned in the product details.
  • Built as a factory-made steel magazine, so it may be a heavier, more rigid option than polymer alternatives, though no weight is specified in the provided data.
  • The matte black Parkerized finish is practical and subdued, but the listing does not provide any claims about wear resistance or long-term finish durability.
