4998 : Ergo Grip® MagBlocker 10 Round
The ERGO GRIP MagBlocker is permanently installed in USGI issue standard capacity magazines to limit capacity to 10 rounds for those jurisdictions where such limits apply.
Made from glass filled polymer. It is the buyer's responsibility to comply with all applicable laws and regulations. The host GI 30rd magazine must have the green follower to work with this product. Once the MagBlocker in installed in the magazine you must install a rivet through the hole in the base plate into the hole in the MagBlocker.
Without the rivet, the MagBlocker will not work correctly. We do not provide the rivet. The size you will need is a 1/8" diameter with 1/4 " grip. The hand riveter with rivets can be found at your local hardware store.
