I am building a personal rifle with a brake and may utilize a thread protector to replace the brake for occasional use when I'll have a hunting partner nearby and don't want the brake's muzzle blast to impact the health of his ears. I always wear protection, braked or not. I know from experience in using a rotating, tunable brake (Que Industries) that the length, weight, position of anything appended to the end of a barrel can affect accuracy. Does anyone have experience to say whether I should be concerned with this? Common sense says build the thread protector to be as close as possible to the mass and shape of the brake.
