  • Information
This Alexander Arms Overwatch AR-15 Upper Receiver Assembly comes complete and ready to fire upon installation onto any standard, small pin lower receiver. The Overwatch is chambered for the high performance 6.5 Grendel cartridge, offering shooters an excellent alternative to the traditional 223 Rem/5.56 NATO round that boasts more power, greater ballistic efficiency, increased effective range and enhanced accuracy potential. To maximize the 6.5 Grendel's effectiveness, this upper features a 24" stainless steel barrel and a rifle length, free floating composite handguard with dual forward sling swivel studs. The A3 flat-top Overwatch comes complete with a low profile gas block, bolt carrier group, charging handle, forward assist, ejection port door, shell deflector, and one 10-round magazine.
