Can a Private Citizen Own One?

8.1 The short answer

No private citizen in the United States can lawfully own an MP7. The weapon is a machine gun, it was first made in 1999, and the federal register of machine guns that private citizens may own closed in 1986. No exception covers it, and no price buys one. The only civilian routes to the experience are a licensed airsoft copy, a semi-automatic gun in the same cartridge, or one of the first semi-automatic guns built to look like it, each covered below with prices taken from the seller’s own page and dated.

8.2 The arithmetic

The hub’s MP 40 dive sets out the federal law in full, quoting the statute, and the FN P90 dive applies it to the MP7’s closest rival. It is not restated here; the argument is short.

1. Since 19 May 1986, 18 U.S.C. § 922(o) has made it unlawful to transfer or possess a machine gun that was not lawfully possessed before that date, except by or under the authority of a government.¹
2. The MP7 is a machine gun under 26 U.S.C. § 5845(b): it fires automatically more than one shot by a single function of the trigger (Volume 5).¹
3. The first PDW prototype was shown in 1999 and the first ammunition and prototype were made in 1995 (Volume 1).²

No MP7 existed before 1986, so none was ever registered before the cut-off, so none is transferable. The P90 dive calls the same result for the P90 “arithmetic, not scarcity”; it applies to the MP7 exactly.³ The MP 40, built in the 1940s, is the hub’s contrasting case: a transferable MP 40 exists because some were registered before 1986.¹

Public Law 119-21 of 4 July 2025, which cut the federal making and transfer tax to $0 for short-barrelled rifles and suppressors, did not reach machine guns: their tax stays at $200, and in any case no transferable MP7 exists to be taxed.¹

8.3 Has H&K ever sold a semi-automatic MP7 to civilians?

No H&K document found offers one, and no evidence of one was found.

• H&K’s current product page lists the MP7 A1 and A2 under “Military & Law Enforcement”, with semi-automatic and full-automatic fire.⁴
• H&K’s US website could not be read for this dive (it refused automated access on 2026-10-18), so a statement from H&K Inc. on its civilian policy was not obtained.
• Every H&K document of 2000 to 2012 used in this dive addresses military, police and VIP-protection users only.²⁵⁶
• H&K has made a semi-automatic-only MP7: the Ministry of Defence Police’s weapons of 2005 were specified single-shot only (Volume 2).⁷ They were made for a police force and are not evidence of a civilian product.

Secondary sources (a suppressor maker’s blog and an ammunition retailer’s guide) say no civilian semi-automatic MP7 exists; they are consistent with everything above but are not H&K’s word, and are not cited as proof.

8.4 Dealer samples, and why they do not help

Machine guns made after 1986 can be held by licensed dealers who pay the special occupational tax, as “post-86 dealer samples”, for demonstration to government buyers. The MP 40 dive’s §6.2 explains the category: such a weapon “belongs to the licensed business and never becomes available to a private citizen”, and does not become transferable through the dealer’s retirement, death or sale.¹ Whatever MP7s US dealers hold in that form are not an ownership route.

8.5 Michigan

Michigan’s machine-gun statute, MCL 750.224, prohibits possession of “a machine gun or firearm that shoots or is designed to shoot automatically more than 1 shot without manual reloading, by a single function of the trigger”, with an exception framed around federal licensing. The MP 40 dive’s §6.6 quotes the statute and discusses the exception; with no transferable MP7 in existence, the question it leaves open does not arise for this weapon.¹ For the semi-automatic alternatives below, a short-barrelled rifle in Michigan carries the state duties set out in the same section (MCL 750.224b).

8.6 No conversions

Converting any semi-automatic firearm to fire automatically is making a machine gun, which § 922(o) forbids a private citizen, and is a felony under Michigan law as well. This hub does not describe how to do it for any weapon, and nothing in this dive should be read as information towards it. The same applies to the fire-control mechanism of the MP7 itself, which this dive describes only as far as H&K’s operator’s manuals do (Volume 5).

8.7 The alternatives

Three lawful things come closest to an MP7 for a private buyer, and they answer different wishes: the look and handling (airsoft), the cartridge (semi-automatic 4.6×30 guns), or both (the first MP7-styled 4.6×30 semi-automatics).

8.8 Licensed airsoft copies

H&K licenses airsoft MP7s through Umarex, and they are the most faithful copies of the weapon that a private person can buy. Deutsches Waffen-Journal reported in 2015 that Umarex’s gas-blowback MP7A1 and MP7A1 “Navy”, made by Vega Force Company in Taiwan, copied the real weapon’s dimensions, weight, markings and pictograms “1:1”, cost €299 each in Germany at the time, and in the German market version were limited to 1.3 J and sold to buyers aged 18 and over.⁸

The full survey of every airsoft MP7 currently on sale in the US, with makers, mechanisms, weights and dated prices from the sellers’ pages, is in the hub’s MP7 light-gun donor dive, Volume 1. In brief, from that survey: the US Elite Force gas-blowback MP7 is made by KWA, not VFC; the electric Elite Force MP7A1 is VFC’s; and a spring-powered single-shot version is the cheapest licensed copy.⁹ The law on realistic replica guns, including the federal marking requirement for toy, look-alike and imitation firearms, is in Volume 3 of the same dive; the hub’s Airsoft gas dive covers the propellants.

Volume 4 of this dive explains how to tell a licensed replica from the real weapon in a photograph.

8.9 Semi-automatic guns in 4.6×30

The cartridge itself is legal for a private buyer, and so are semi-automatic guns chambered for it.

CMMG Banshee Mk4 in 4.6×30. CMMG’s own page lists the “PISTOL, BANSHEE, Mk4, 4.6X30MM, 8"", product number 46A870D, at $1,549.95 (cmmg.com, 2026-10-18). It is a direct-impingement AR-pattern pistol with an 8-inch barrel, weighing 4.3 lb and 23.7 in long, supplied with a CMMG 40-round magazine; the page does not say whether it accepts H&K magazines. CMMG describes the cartridge as “First introduced in 1999” and “known for its pairing with the Heckler & Koch MP7”.¹⁰ It shares the MP7’s cartridge and nothing of its mechanism or appearance.

8.10 MP7-styled semi-automatics

The first semi-automatic guns built to look like the MP7 and fire its cartridge are recent, and the field is thin.

UO Arms NT7. UO Arms LLC of Dallas, Texas, lists an “NT7 Pistol 4.6x30mm Semi-Automatic Gas Operated Firearm” at $3,499.00, with “Anticipated delivery … Q4 2026”, not shipped to California, Maryland or Massachusetts, with an adjustable gas block, flip sights and one magazine (uoarms.com, 2026-10-18). The page names neither H&K nor the MP7. UO Arms also lists an NT7 SBR.¹¹ The Firearm Blog (11 September 2026) introduced the SBR as “the closest civilian equivalent” to the MP7, gave its price as $3,798.00 with the pistol “a little less”, reported that UO Arms makes its own magazines, and said its writer did not know whether the gun used a rotating bolt or blowback.¹² The NT7 had not shipped when this dive was written; its mechanism, magazine compatibility and resemblance in detail could not be checked.

A short-barrelled rifle such as the NT7 SBR is a National Firearms Act item: registration and approval are still required although the federal tax is now $0, and Michigan adds its own SBR duties (MP 40 dive, §6.3 and §6.6).¹

Others reported but not verifiable. Trade press reported an MP7-styled 4.6×30 pistol by Tommy Built Tactical at the 2024 SHOT Show; on 2026-10-18 that company’s web address served unrelated spam, so the product could not be checked on its maker’s page and is not described. A 5.7×28 “PDW concept” shown by another maker at the same show had no product page that could be found. Home-made and 3D-printed lookalikes are outside this dive’s scope.

8.11 Ammunition

4.6×30 is sold to US civilians. A Midwest Gun Works listing for “Fiocchi Range Dynamic 4.6x30 40gr. FMJ 50 Rounds”, code 46EXA, showed $39.99 for 50, in stock, at 1,900 ft/s (midwestgunworks.com, 2026-10-18); Fiocchi’s own product page could not be found.¹³ It is a lead-core full-metal-jacket target load, not the hardened-steel bullet of the military loads. Volume 3 explains why the statutory definition of armour-piercing ammunition, which turns on what a bullet is made of and on whether it “may be used in a handgun”, now has 4.6×30 handguns to attach to in the US market.
