YHM SRX QD Adapter

The YHM SRX QD Adapter is engineered for everyday carry users who prioritize a sleek, low-profile suppressor setup combined with ease of use. This adapter attaches to the industry standard 1-3/8” x 24 threaded barrel and features an internal taper seal that locks the suppressor securely while preventing gas and debris buildup on the threads.
