Delta Armory Mock Bolt Catch for M4/AR-15 AEGs

If you've lost your bolt catch, you're in luck! The Delta Armory Mock Bolt Catch for M4/AR-15 AEGs is a replacement original part for Delta Armory M4/AR-15 AEGs but may also fit certain other brands, provided they don't have a functional bolt catch and use a bolt catch style which sits in the receiver recess and isn't retained by screws or a pin. This bolt catch is constructed from alloy and is the standard milspec design.
