Ultra Defense Corp(UDC) 5.56x45mm M193 55 Grain Full Metal Jacket(FMJ) 3250 FPS - 250rd/Box

Built by a US Government Ammunition Contractor. Priced for the Range.

Ultra Defense Corp doesn't primarily load ammunition for civilians — they load it for the US Army, SOCOM, and America's allies. This 5.56x45mm 55gr M193 comes off the same production line, held to the same tolerances, and inspected under the same ISO 9001:2015 quality system that governs their federal contracts.

Highlights:

• Loaded by Ultra Defense Corp — prime contractor on the US Army's $490M SAWS and SOCOM's $750M SUMR ammunition contracts
• ISO 9001:2015 certified manufacturing facility
• St. Marks Powder propellant — the same mil-spec supplier used in US military 5.56 production
• CCI primers, General Dynamics projectiles, General Dynamics brass cases
• Independently tested: average muzzle velocity 3,079 fps, average pressure 38,890 psi (well within 5.56 NATO spec)
• Registered with the US Department of State and Department of Justice as a manufacturer of defense articles
• American-owned small business, headquartered in Tampa Bay, Florida

Detail: When you're paying for defense-contractor-grade ammunition, you're paying for the QC infrastructure that comes with it — the lot testing, the traceability, the pressure and velocity verification on every production run. UDC's civilian ammunition is the same product, built to the same standards, with lot test data available on request.

Please note: Cases and primers are not sealed. This ammunition is ideal for range training, competition, and defensive practice. For long-term storage in humid or wet conditions, sealed alternatives are recommended.
