(NOT COMPATIBLE WITH CONVERSION BARRELS)

 *Compensator may require tuning of Recoil System. Designed to work with most factory loaded ammunition but will yield the best results with a heavier charged ammunition*

The package includes:

118 Comp (Generation specific) 

2 Set Screws with an Allen Wrench

  ** These compensators are designed to fit best with Agency Arms barrels, some aftermarket barrels have different standoff distances which can cause a gap between the compensator and slide*
