Runs good. Brand is Golden Eagle and takes WA parts. Some parts are ghk compatible like the bolt assembly mag and hop up some ghk parts to fit might require modifications it’s completely stock other then the cut inner barrel and shorty hand guard, stronger recoil spring, compensator and a SS buffer in the rear buffer tube so i should mention it won’t lock back. Comes with the sling and red dot battery included. Originally this was a 9in with its had guard and outer barrel, it will be included. Only thing wrong with it is it could use a clean up inside. I bought this back in June. Update as of Aug 30; I ported the nozzle crown next to the valve for higher gas flow and added a 60 Mr. Hop bucking. The charging handle broke for now it’s got a TPU replacement one.
