UO Arms NT7 SBR

The UO Arms NT7 SBR is the factory short-barreled-rifle configuration of the NT7, a semi-automatic civilian clone of the Heckler & Koch MP7 chambered in 4.6x30mm and built in Dallas, Texas. It is the reengineered continuation of the Tommybuilt T7; founder Tom Bostic wound down Tommy Built Tactical and moved the platform to UO Arms, which states it was reworked to meet industry-standard quality, performance, and reliability. It runs the MP7's gas-operated action, weighs 3.6 lbs, and measures 23 inches with the stock extended.

The SBR configuration carries a three-position collapsible stock and a two-position M-LOK foregrip over the pistol variant's hardware. The platform uses an adjustable gas block, an M-LOK handguard, top and side Picatinny rails, ambidextrous controls, and QD sling attachments, and it ships with flip-up sights and one magazine. A HUXWRX flash hider and suppressor mount comes installed for the purpose-built HUXWRX 4.6x30mm flow-through can that UO Arms sells alongside the gun. Magazines are offered in 10, 20, 30, and 40-round capacities.

This is a proprietary, premium specialty firearm rather than a general-purpose PCC. Magazines and furniture do not cross with other platforms, 4.6x30mm ammunition (produced by Fiocchi and Federal) is thinner on shelves than common pistol calibers, and the SBR configuration is an NFA item requiring a Form 4 or Form 1 registration. The federal tax on short-barreled rifles is $0 under the One Big Beautiful Bill Act. UO Arms sells the NT7 factory-direct.
