UO Arms has opened the order books on the NT7, a US-built semi-automatic pistol chambered in 4.6x30mm that brings a compact PDW format to the civilian market in two configurations: a pistol at $3,499 and a factory short-barreled rifle at $3,798. The Firearm Blog reported the launch, calling the NT7 the first US-manufactured civilian-legal 4.6x30mm platform to reach commercial availability. Orders placed now carry an anticipated Q4 2026 delivery window.

The NT7 traces its design lineage to the Tommybuilt T7, a 4.6x30mm platform that Tom Bostic developed and later brought to UO Arms, where the design was reengineered for domestic production at higher volume. Rochefort Asset Management closed a senior secured loan to UO Arms in January 2026 to accelerate production capacity and advance development of the NT7 line, positioning the company to fulfill early orders and support commercial availability through the second half of the year.

The action is gas-operated. Buyers can configure the pistol in four finishes — black, grey, RAL, and flat dark earth — and select from 10, 20, 30, or 40-round magazine options. The SBR version arrives pre-configured with a three-position collapsible stock, a two-position M-LOK foregrip, and a HUXWRX flash hider with suppressor mount already fitted at the factory. UO Arms is also offering a purpose-built HUXWRX 4.6x30mm flow-through suppressor as an add-on for $999.95 — a tight integration that keeps the suppressor footprint proportional to the platform's compact dimensions.

The 4.6x30mm cartridge is a bottlenecked, high-velocity intermediate round designed for the PDW role. Commercial ammunition is available from Federal and Fiocchi, though selection remains more limited than mainstream pistol calibers. The caliber's smaller case head gives the NT7 a slimmer, lighter profile than 9mm-chambered PDW-style pistols, which is part of what makes the format appealing to buyers looking for maximum compactness with higher round count.

The SBR configuration requires NFA approval and a tax stamp before taking possession, meaning buyers will need to factor ATF processing time into the Q4 delivery timeline. The pistol version carries no such requirement. Both configurations are sold through UO Arms' authorized dealer network.

The NT7 fills a gap in the civilian small-arms market that HK's MP7 has occupied in the military and law enforcement world for years. With no direct competition from an imported civilian-legal 4.6x30mm platform, UO Arms enters the segment with little resistance on the specification side — the question for buyers will be whether pricing and lead times hold up once first-run units ship.

Watch for initial range reports from early customers as the Q4 window opens, and for UO Arms to expand its dealer footprint ahead of deliveries.
