A SilencerCo thread spacer for 1/2x28 rifle threads, adding a quarter inch of standoff. Thread spacers solve a very specific and very common problem: when a muzzle device or suppressor mount times out of alignment or bottoms out before it fully indexes, a spacer lets you dial in correct shoulder contact without cutting or shimming the barrel.

Proper shoulder contact matters enormously with a suppressor, since a device that is not fully seated and squarely aligned risks a baffle strike. Precision-machined by SilencerCo to their own suppressor tolerances.
