IMPORTANT: The SIG Sauer M400 Elite 16" .223 is classified as a prohibited firearm in New Zealand under the Arms Act 1983 amendments, specifically those enacted in 2019. This means that general civilian ownership of this semi-automatic rifle is prohibited. The SIG Sauer M400 Elite is available exclusively to authorised personnel and entities in New Zealand who possess the appropriate permits and endorsements, such as government agencies, law enforcement, legitimate security organisations, or primary producers with specific E-Category endorsements for restricted firearms.

The SIG Sauer M400 Elite continues the brand's tradition of delivering dependable firearms. Since 2010, the M400 has been a successful rifle platform, recognised for its reliability, accuracy, and features that set it apart. For authorised users in New Zealand, this SIG M400 offers an accuracy-driven AR system equipped with desirable features, making it a highly sought-after SIG AR model.

This M400 Elite model maintains the exacting standards of the original while incorporating upgraded components, making it a high-performing rifle straight out of the box. Key upgrades include a lightweight, full-length, free-floating M-LOK® handguard, which ensures consistent, unimpeded accuracy and promotes better handling. This valuable component, often an aftermarket addition, surrounds a 16-inch, 1:7-inch twist barrel with a SIG Micro-Light Gas Block™, weighing just half an ounce.

The SIG Sauer M400 Elite ships with upgraded furniture, moving beyond a standard M4-style stock and A2 grip. It features a SIG Enhanced six-position buttstock for optimal length of pull and an Enhanced SIG Pistol Grip for improved control during firing. Another enhancement is the SIG Enhanced single-stage trigger, providing a lighter pull and crisper feel. Together, these improvements deliver an accurate, lightweight, and dependable AR rifle for authorised users, making it a top choice among .223 rifles.

To complete the system, the M400 Elite can be acquired with or without the company’s ROMEO®5 red-dot sight installed. This sight enables fast, accurate target acquisition and features SIG SAUER Motion Activated Illuminated (MOTAC®) technology, which turns on with motion and powers down when not in use, extending battery life to 40,000 hours.
