Money well-spent
Ordered this BCG, along with an Odin Works hand guard for an SBR build…amazing how durable the finish on the BCG is…even when running it suppressed, which cruds up other similar components, this one just wipes off! Pretty-much nothing sticks to it.
United Statesfreaking impressed

United StatesAs advertised
Works like it should. Haven't had a chance to use it. Bought it to replace a BCG that wouldn't even allow me to load a round in the chamber. Popped this in and it was smooth as butter.
