The short answer: there is no way for a private citizen to buy a new H&K MP7, but there are now two civilian routes to something shaped like one in 4.6x30mm, and both can be run suppressed. Here is what is real, what is announced and what you should check before you spend money.
Why you cannot just buy an MP7
The MP7 is a select-fire 4.6x30mm submachine gun. According to American Gun Trader's 2026 overview, existing MP7s are post-1986 machine guns that cannot be transferred to private citizens, and any transferable one would be speculative and likely run past $50,000. That is why most searches for a "suppressed MP7 SBR" end at the same place: a civilian semi-auto in the same cartridge, registered as an SBR, with a suppressor on top.
Option one: UO Arms NT7
As we reported in September, UO Arms started shipping the NT7, a civilian short-barreled rifle in 4.6x30mm modeled on the MP7. Reported details include a package under 16 inches, a roughly 9-inch barrel, a folding stock and a short rail system. It comes either as a bare receiver or as a complete build. Reported pricing starts around $2,200 for the complete package, and reported all-in cost lands between $2,800 and $3,400 once you add an optic, ammunition and paperwork. Ammunition is the real expense: that piece estimated $1.25 to $1.75 per round. Read the original DownRange news report on the NT7.
One correction on that report. It cites a $200 tax stamp for the Form 1. That tax went to $0 on January 1, 2026, so the paperwork cost is now the time, not the stamp.
Option two: HK SP7, announced but not here
Rifle Configurator reports H&K has announced the SP7, a semi-automatic civilian MP7 in 4.6x30mm with a 7.09-inch barrel and no stock. The article says Germany's federal criminal police office (the BKA) classified it as a semi-automatic short firearm and that it still needs ATF import approval, with no firm US timeline. A dealer listing of $2,500 and a "Q4 2026" tag is described as a placeholder pre-order price, and HK USA has not confirmed pricing. Until HK USA confirms import, treat it as vapor.
How the NFA part works in 2026
- The tax is $0 for suppressors, short-barreled rifles, short-barreled shotguns and Any Other Weapons, effective January 1, 2026 (One Big Beautiful Bill Act, signed July 4, 2025).
- Registration is not gone. You still file an ATF Form 1 to build an SBR or a Form 4 to buy a registered item, with fingerprints, photos and a background check.
- An SBR and a can are two separate items, so a suppressed SBR means two approvals.

Before you order
- State law first. Some states bar SBRs or suppressors outright. Check your state on My State.
- Match the can to the cartridge. Confirm the suppressor's rating covers 4.6x30mm and your mounting interface before you file.
- Budget for ammo. At $1.25 or more a round, 4.6x30 is a range-day luxury.
My take: the NT7 is the only one of these you can actually order today, and it is a fair answer to a long-running request from gun owners. I would still wait for independent test results on reliability before putting a four-figure build on the Form 1 line.
