Description

Part of the STEYR BREEZER OSD suppressor series, the SD‑988514 variant is engineered to provide effective sound suppression through STEYR’s “Virtual Volume” technology, which maximizes suppression performance without adding unnecessary weight or bulk. The design is an over‑barrel silencer, meaning it extends back over the rifle’s barrel, helping to reduce the total added length and improving balance on the firearm.

These suppressors are typically around 228 mm in overall length, 45 mm in diameter, and weigh approximately 400 g. They achieve sound reduction on the order of ≥ 33 dB(A) at the shooter’s ear for .30‑class calibers. Thread options available for the OSD series include M14×1, M15×1, M18×1, and ½‑20 UNF, with M18×1 being the correct thread for this particular SKU.
