Factory brake is ok, but after markets perform better. Weight and the trigger is the biggest thing with Strikers. I have varmint weight barrels 17" long on mine and have added weight to stocks. A Ross Shculer muzzle brake and your gun won't move. No experience with the super striker stocks here. I have a heck of a shooting striker forsale on here now if your deal doesn't go through. I have never paid more than $550 for a striker.
