I am new to the NFA arena and I am looking into getting a few items. 300 Blackout SBR and a suppressor. I am going the gun trust route. My question is what requirements is there for storing these items. I think class 3 weapons you have to have a certain type of gun safe ect. Is this the same with suppressors and sbrs. or do they just have to be secured in a gun safe? Are there any other things I need to plan for or worry about before I start this journey?
