| I recently recieved a front flip up sight base fron PRI and i know you have to take off the flash hider to get the origional base off and i know i will need a new crush washer but is there a standard way to properly time the gas tube to the gas block part of the sight base with great confidence. If yes how, if not then how should it be done. |
