Don't let the size fool you - the Silent Steel USA Compact Streamer packs full-size performance into a shorter, more maneuverable form. Featuring the same advanced FLOW-IQ technology as the full-size model, it effectively reduces blowback and recoil while keeping your rifle balanced and agile. Ideal for shooters who demand suppression, the Compact Streamer delivers low-gas, low-signature performance in a lightweight, rugged, and easy-to-maintain package. HUB Mount 1 3/8x24
