SilencerCo Rifle Thread Spacer 1/2x28

The SilencerCo Rifle Thread Spacer 1/2x28 is a precision-engineered adapter designed to facilitate sound suppressor mounting on rifles threaded to the 1/2x28 standard. This spacer serves as an essential interface component for operators and shooters who require repeatable, indexable suppressor attachment across multiple host firearms or who need to accommodate specific suppressor mounting requirements without permanent barrel modifications.

The 1/2x28 thread specification is the industry standard for most centerfire rifle platforms in the 5.56 NATO and similar caliber classes. By isolating the suppressor mounting interface from the barrel itself, a dedicated spacer ensures consistent suppressor indexing and allows for modular reconfiguration across different shooting platforms. This is particularly valuable for shooters managing multiple AR platforms, designated marksman rifles, or precision rifles where barrel threads may have accumulated wear or where temporary suppressor installation is preferred over permanent integration.

This component is essential for precision shooters, law enforcement tactical teams, military operators, and civilian rifle enthusiasts who run suppressed systems. It addresses the practical requirement of maintaining clean suppressor attachment across rifles with varying barrel conditions, thread pitches that differ slightly due to manufacturing tolerance stack-up, or situations where a single suppressor needs to transition between different host weapons. Proper thread spacer selection ensures reliable suppressor mounting and prevents cross-threading or loose indexing during deployment or training cycles.
