- Abdullah Celer, President and CEO of Derya (Jacksonville, FL USA)

OBone brings a .22 LR host down to the 112 dB range* in a package that weighs less than four ounces (3.99 oz) and adds just 5.25 inches to the muzzle. Eight identical 7075-T6 aluminum baffles stack in any order — no numbering, no wrong way round — inside a black-anodized tube, behind a screw-on 4140 steel mount with a black nitride finish. Every part separates by hand. When rimfire lead builds up, you soak, brush, and reassemble; no tools, no shop visit.

The steel mount carries the serial number and threads directly onto any ½"-28 rimfire barrel, pistol or rifle, with no minimum barrel length. OBone is full-auto rated in .22 LR and rated for semi-automatic fire in .17 HMR and .22 WMR.

Engineered and built in Jacksonville, Florida, and backed by Derya's Limited Lifetime Warranty. Actions Speak Louder™.

*Representative result with .22 LR; varies with host, barrel length, ammunition, temperature and metering method.

Four Ounces of Quiet

OBone takes a .22 LR host to the 112 dB range while weighing just 3.99 oz and adding only 5.25 inches to the muzzle. Its slim 1.181-inch profile balances on a pistol as naturally as on a rifle, so the gun still handles the way it did.

Eight Baffles, Zero Guesswork

Eight identical 7075-T6 aluminum baffles make up the stack. They aren't numbered and have no set order, so there's nothing to track while you clean. Stack them facing the right way, drop them in the tube and you're back together in seconds.

Cleans Up by Hand

Cleans Up by Hand

Rimfire runs dirty. OBone is fully user serviceable: the front cap, tube, baffle stack and mount all come apart by hand, no tools needed. Soak the parts, brush them with an aluminum-safe cleaner, then reassemble. No shop visit, no special wrench.

Steel Where It Counts

The serialized mount is 4140 steel with a black nitride finish, so steel carries the threads. The tube, baffles and front cap are black-anodized 7075-T6 aluminum. It threads onto any ½"-28 rimfire barrel with no adapters and no minimum barrel length.
