The Elite Ti configuration pairs forged 7075-T6 aluminum receivers with a durable Titanium Cerakote finish. The direct-impingement action is complemented by the SIG Enhanced single-stage trigger and the SIG Micro-Light gas block, delivering the Elite-series feature set in a factory package.
The 16-inch barrel uses a 1:7 twist and a threaded muzzle, fitted with an open three-prong flash hider installed with a crush washer. This setup offers a practical, ready-to-use barrel assembly in the 5.56mm NATO chambering.
A free-float aluminum M-LOK handguard features an unnumbered top rail and carries a small "PAT. PEND." marking; T-number reference marks are present on the upper receiver rail. Standard AR-15 features are present, including a forward assist, ejection-port cover, and brass deflector. This rifle ships without sights.
The black polymer 6-position collapsible stock includes a QD sling socket, paired with a SIG-branded textured polymer pistol grip. The lower uses a detachable AR-15/STANAG magazine interface and includes one MFT GEN2 30-round magazine. Receiver roll marks read "SIG SAUER SIGM400" with "SIG SAUER INC, NEWINGTON NH, USA," and the magwell bears the SIG round logo. A factory case label with matching serial was observed.
