How to customize your “kit”


  1. Start by picking your handguard converter nut below. The “Standard” nut leaves a 1/4″ gap, while the “Modified” nut leaves a 3/32 inch gap, but also requires permanent modification of your upper. Learn more.
  2. Next, in each step, pick any additional tools that you need to complete your kit. While optional, these other tools are HIGHLY RECOMMENDED. If you do not purchase everything you need here, you may be unable to complete your conversion!
