.50 call radial muzzle brake threaded 3/4x20. The CVA lrx, mrx, and original paramounts are this thread pattern. Brake is from Arrowhead rifles and is overbored to shoot sabots. Have not had any issues. Arrowhead sells a funnel that you can push a .50 cal bullet through in the loading process, works well.
$50 TYD Venmo works best.
