Operators Suppressors
The OSS RAD Direct Thread Adapter in 1/2-28 is a precision-machined mounting solution for shooters running suppressor-ready barrels. If you're building a suppressed rifle or pistol around a RAD suppressor system, this direct thread adapter provides a rock-solid connection between your muzzle and your can—no additional brake or muzzle device needed. It's purpose-built for fixed-barrel applications where reliability and a compact footprint matter.
Machined from 17-4 stainless steel, the adapter is heat-treated and finished with black nitride coating. That combination delivers real durability: nitride resists wear from repeated installation and removal, and handles corrosion better than bare steel. The wrench flats let you tighten it down securely without guessing whether you've got it hand-tight enough.
This adapter is engineered for fixed-barrel systems only—don't use it on short-stroke piston or other unlocking/reciprocating designs, since the recoil impulse would hammer the threads. It threads onto barrels with 1/2-28 pitch and pairs directly with RAD 9 and RAD 45 suppressors, so verify your barrel's thread pitch and suppressor model before ordering. If your rig meets those requirements, this is a no-frills way to mount a can and get shooting.
| Thread Pitch | 1/2-28 |
| Material | 17-4 Stainless Steel, heat-treated |
| Finish | Black Nitride |
| Compatible Suppressors | RAD 9, RAD 45 |
| Barrel Type | Fixed-barrel systems only |
This adapter is designed to thread directly onto RAD 9 and RAD 45 suppressors. Verify your suppressor model and your barrel's thread pitch (1/2-28) before purchasing.
No. This adapter is engineered for fixed-barrel systems only. Do not use it on unlocking or reciprocating barrels, as the recoil impulse will damage the threads and adapter.
You receive the direct thread adapter. Installation requires a wrench to tighten it onto your barrel and suppressor using the wrench flats provided.
Black nitride coating improves wear resistance against repeated installation and removal, and protects the stainless steel from corrosion. It's a tough finish built for the abuse of field use and regular can swaps.
