SRC Adapter 14mm CW to CCW

The SRC Adapter 14mm CW to CCW makes it possible to turn your CW (Clock Wise) outer barrel into a CCW (Counter Clock Wise) barrel.

The CW thread is not that common anymore and there are many silencers for example that are only available in CCW. You could also look at silencers that have the combination CW and CCW, there are already quite a few of those available and you don't need this adapter.
