CNC lathe turned from impact resistant polymer. Replaces the steel insert supplied with the law folding stock adapter kit and must be used for all FX-9 platforms. This bolt carrier extension is compatible with LAW Gen 3 folding stock adapter.
** WARNING** If using this on our FX-9 (4in Pistol configuration) you will need to purchase the light weight spring and buffer combination to get ammunition to cycle depending on the type of ammunition being used. You may only need to use the lightweight buffer, but in extreme cases, with weaker ammunition, you will need to use both spring and buffer. We recommend using just the buffer initially and if your ammunition cycles, use the stock spring.
***WARNING*** If the LAW folding stock adapter mechanism is removed from the firearm, you MUST replaced the buffer system with original components or damage to the bolt and bolt hold open will occur.
