Freedom fighter refill kit - Hogue Fixed Magazine Solution Kit Refill

The best fixed magazine solution for making your AR15 California compliant also comes with an available refill kit, which comes with three additional grub screws, pins, and springs so you can avoid buying the jig all over again if you have already purchased one in the past. I purchased both at the same time, knowing I had several rifles to modify. I would recommend this to anyone with basic mechanical skills, as it can be a bit tricky to install the first time. As with anything else, becomes easier to install with practice. My only complaint is that it is not available for the AR10 platform to my knowledge.
