Silencerco Osprey Octane Fixed Barrel Spacer Compact 17-4 Stainless Steel

Transform your SilencerCo pistol suppressor for fixed barrel applications in minutes. This precision-machined spacer replaces the booster spring in your Nielsen device, allowing you to run suppressors such as the Osprey, Octane, Omega K, or Hybrid 46 on pistol caliber carbines, subguns, and other fixed barrel firearms.

Nielsen devices (boosters) are designed to allow proper cycling on tilting barrel handguns, but on fixed barrel platforms like PCCs and subguns, that movement is unnecessary and can reduce consistency. This spacer locks the system solid for optimal stability and performance on fixed barrel setups.
