So far so good - RISE Armament OpticsPlanet Exclusive RAVE 140 With AR-15 Lower Parts Kit

The BCG is solid. So far only 500 rds through it but the bolt face looks good, gas rings are solid. Whatever the coating is they use on it seems to be pretty good. It stays slick even with little to no lube. It’s not BCM or Geisle but for the cost I would recommend it. The trigger is a nice upgrade. Smooth crisp break and a really nice reset. Big upgrade over mil spec. No malfunctions or light strikes. Good stuff. I haven’t replaced the internals yet but those small parts feel like good quality.
