ET Arms ETAGOMEGA556ML15 | Omega-15 5.56 16in 15in M-LOK

The ET Arms ETAGOMEGA556ML15 (RIA Omega-15) is an AR-pattern semi-automatic rifle built around a 16″ 1:8 twist barrel and a 15″ M-LOK handguard. It ships with flip-up sights and a black finish, and includes a carbon fiber buffer tube with an ATI stock. For an optic under $1,000 that pairs well for both close-to-mid-range precision and competition use, consider a Vortex Strike Eagle 1-6×24 or a Sig Sauer Tango4 1-4×24.

Applications: duty-style precision at mid ranges and action shooting/3-Gun competition are appropriate real-world uses for this configuration.
