BRN-180 v2 File Drop

This is an update on the first BRN-180 monolithic lower I uploaded in 2022. The biggest change is the grip angle, it's closer to 12 degrees and way more comfortable for shorter stocks and pistol braces. There is a small area cut next to the safety that can be filled with a red paint pen to help people know when the safety is on or off. You would be surprised how many gun owners can not understand the AR safety when handed a blank one.
