This 12mm diameter magnetic steel armature designed for the GR-series accelerators. This is the only ammunition recommended for such accelerators. Box of 81.
These are literally just 3/8″ concrete anchors with the center plug removed. You can purchase them from your local hardware store or online at many retailers. We sell them here for the sake of convenience. If you choose to purchase them from a third party retailer, MAKE SURE YOU remove the center plug from the anchors. Failure to do so could result in a hard barrel jam and irreparable damage to the barrel.
Although it is possible to fabricate your own armatures and fire them from the GR-series accelerators, we discourage such actions and caution users against using home-made or non-OEM armatures since such armatures could degrade, jam or score the barrel or foul the optical gates.
