Any opinions on whether or not it would be legal to build and hunt deer in Illinois with the following configuration?
New AR lower receiver registered as "other firearm" on the 4473 (never registered as a rifle and stock never installed)
Bullet button installed
Bob sled "magazine" installed
SB Tactical adjustable arm brace installed on pistol buffer tube
16" upper chambered in 300 Blackout
Magpul angled foregrip
If it is not a legal configuration, what would need to be changed to make it legal to own and hunt with? If it is legal to build this configuration, is it legal to shoot from the shoulder if the brace has not been modified?
I apologize if some of these questions have already been asked in previous threads. Thanks in advance for your input!
