I'm getting ready to start my first AR build, and am pretty sure I am going to purchase all the parts in kits, rather than assemblies. I am in MA, so I have to pin/weld stuff
For the Butt-stock, at what point after assembly must it be pinned? What about the muzzle brake?
Does that have to be done before final assembly so I don't end up with something bad in my possesion? Can I test fire with the stock at various lengths before I decide where I want to pin it?
