Could someone please recommend a 5.56 muzzle device (which type, brand and model is better?) to be used with the 5.56 Polonium K suppressor? The intent is to shoot that BCM AR both with and without suppressor in an easy way - just screwing on and off the suppressor. I would consider both budget and ellite option. Anyway, it still beats me how a simple piece of metal in a relatively simple shape cost up to $180.
