Expanding its footprint in the American market with its very first domestically manufactured sound suppressor, Derya Arms has officially introduced the OBone. Designed and built at Derya’s Jacksonville, Florida facility, the OBone is a dedicated rimfire silencer engineered to deliver high-performance suppression, full-auto durability in .22 LR, and user-friendly maintenance at an aggressive $199 MSRP.

Mechanical Engineering & Metallurgy Science
The OBone’s architecture focuses heavily on longevity and ease of owner maintenance. Rimfire suppressors are notoriously plagued by lead and carbon accumulation that can fuse internal components together. Derya tackles this by engineering the mount out of rugged 4140 steel with a black nitride finish, ensuring the high-stress barrel threads live in steel rather than soft aluminum.
The body and baffle stack utilize 7075-T6 aluminum to keep total weight down to just 3.99 ounces, ensuring the suppressor does not negatively alter the balance of lightweight rimfire pistols or rifles. Inside, the OBone utilizes eight identical 7075-T6 aluminum baffles. Crucially, these baffles are non-indexed and feature no set stacking order, eliminating user guesswork during reassembly.
Tactical Utility & Field Maintenance
In the field, a rimfire suppressor must be lightweight enough for nimble pistol work and simple enough to clean after high-round-count training sessions.
Because the OBone features an entirely tool-less breakdown design, all major components—the front cap, tube, unindexed baffle stack, and steel mount—separate cleanly by hand. Shooters can easily soak and brush the aluminum components with standard cleaning solutions without needing proprietary wrenches or factory service visits.
Concluding Assessment
The Derya Arms OBone is a disruptive entry into the rimfire suppressor market. By combining intelligent metallurgy (steel threads paired with aluminum weight savings), an any-order baffle stack, and a $199 price point, Derya delivers an exceptionally practical tool for rimfire shooters.
