The Maxim Defense MD:15 Other Weapon (brand part no. MXM-49228) is a federally regulated NFA Title II Any Other Weapon (AOW) built around Maxim’s 5.56 NATO MD:15 platform, engineered for shooters in New Jersey and other restrictive states where its AOW classification allows a configuration that state assault-weapon laws would otherwise prohibit as a standard rifle or pistol. Maxim Defense builds the MD:15 Other Weapon around a 12.5-inch threaded barrel paired with a faux suppressor, a free-floating M-LOK handguard, and MIL-SPEC AR-15 internals for reliable function. The optic-ready upper accepts a direct-mount red dot. Because it is classified as an AOW rather than a standard pistol or SBR, this item transfers through the same ATF Form 4 process as a suppressor or short-barreled rifle, requiring an NFA-licensed dealer and a completed background check before delivery. Among our AR pistols, the MD:15 Other Weapon suits buyers who specifically want a state-legal, NFA-registered configuration from a genuine Maxim Defense build.

Frequently Asked Questions

Is this an NFA item? Yes. This is classified by the ATF as an Any Other Weapon (AOW), a National Firearms Act Title II category. It must transfer through an NFA-licensed (SOT) dealer via ATF Form 4, with a background check and approval before you can take delivery.

What does the transfer cost and how long does it take? As of January 1, 2026, the federal transfer tax on AOWs (previously $5) was reduced to $0. You will still need to work with an SOT dealer and wait for ATF Form 4 approval, which can take weeks depending on current processing times.

Why is a New Jersey-legal AR-style build classified as an AOW? Its faux suppressor and configuration place it outside the ATF’s standard rifle and pistol definitions, making it an AOW rather than a regulated ‘assault weapon’ under New Jersey’s state features test.
