Lower Receiver Group Buy

[Auger Precision]

Quick couple questions, Why is bottom of the trigger guard open? I have seen built closed. And why have a button to open the bottom trigger? For what purpose?

for shooting with gloves (thick winter gloves). you can take the tip of a bullet and use it to push the button and swing the guard down.

upper + lower + stock is this legal? I mean no barrel does this make it a sbr?

no. with no barrel its not even a complete gun. legally its not even considered a rifle yet. just a lower receiver. once it has a barrel though, then its a rifle (or an SBR if you went short).

You beat me to it. Short Barrel Rifle. No B no SBR

Now the button thing on the trigger guard makes sense. I just don't ever think I will need use it. Nice to know it is there.
