Bolt catch spring


If you have any doubts in your ability to perform the following actions, stop immediately and seek assistance from a qualified gunsmith. If you need clarification on any of the steps below, please contact us to speak with a member of our support team.

Always wear proper personal protective equipment (PPE) including adequate eye protection when servicing a firearm.

  • You may notice that your bolt catch seems a bit loose or 'wiggles' more compared to a normal AR-15. This is completely normal. In an AR-15, a heavier bolt catch spring is used. This heavier spring puts more tension on the bolt catch. Our receivers use a lightened bolt catch spring to allow the proper function of the last round bolt hold open.
  • Sometimes the bolt catch set screw can become loose. Verify that your set screw is snug. Be careful not to over tighten the screw as you can strip it.
