The LANTAC DMR Upper Receiver is chambered in .223 Wylde with an 18-inch barrel, designed for designated marksman applications on AR-15 lower receivers. The .223 Wylde chamber provides match-grade accuracy with both .223 Remington and 5.56 NATO ammunition, making this upper a versatile choice for precision shooting at extended ranges. This is a complete upper assembly ready to mate with any mil-spec AR-15 lower.
