The design combines an aluminum receiver with steel barrel construction and reinforced components in designated high-wear areas. A free-floating handguard, non-reciprocating charging handles on the rear and side, and the Matchlite Duo Curved trigger define the control layout. The adjustable gas system and piston operating design give this 516 G3 a distinct configuration from direct-impingement AR rifles. The result is a feature-specific 16-inch rifle built around the Sig Sauer 516 G3 platform.
