The X-15 is an X Products aluminum drum magazine for AR-15 and M16-pattern 5.56x45 mm / .223 Remington firearms. Available sourcing centers on its 50-round X-Series design, firearm compatibility, loading method, and patented feed-mechanism context rather than independently documented battlefield employment.

Timeline

X-15 drum magazine Key Events

  1. X-Series development claim

    X Products states that its X-Series magazines were developed in 2005 before entering production later in the decade.

  2. Commercial production begins

    X Products describes 2009 as the production start for the X-Series and says the family introduced an all-aluminum compact high-capacity drum architecture.

  3. Feed-mechanism patent priority date

    The Google Patents record for US8919022B2 lists a 2010-11-04 priority date for the high-capacity firearm magazine feed mechanism later assigned to X Products LLC.

  4. US8919022B2 granted

    The patent record lists the feed-mechanism patent's grant and publication date as 2014-12-30.

  5. Washington restrictions drive production pause context

    X Products links its X-Series pause to Washington's 2022 large-capacity-magazine restrictions; Washington's attorney general described SB 5078 as barring sale, attempted sale, manufacture, and distribution of high-capacity magazines.

  6. Limited X-Series return announced

    X Products announced limited 2026 production runs for X-Series drums, naming both X-15 and X-15 Skeletonized among the listed family members.
