The Inner Bolt Catch is a genuine VFC internal replacement designed to complete the bolt catch system in M4/M16 AEG replicas. This mechanical part links the external bolt catch lever to the internal mechanism, allowing the dummy bolt to be snapped shut with a click while the bolt is held rearward. Especially useful during hop-up tuning it removes the need to prop the dummy bolt open manually, repeatable setup for adjustments. Manufactured to VFC tolerances for a direct fit and consistent mechanical behaviour.
