At SRS we saw the need for a short but extremely effective brake. So we stretched the ports out to increase bore exposure, and “The Chub” was born. All the while coming in at only 1.9” OAL. Made from grade 5 titanium, this brake comes in at a scant 1.6 oz. We use a smooth nut for a sleek look as opposed to an oversized hex style nut. The OD is .990”, and the threads are 5/8-24.
