“I try to stay out of gray areas with BATF”
Absolutely! These folks building 80% guns are nuts if thy think the gooberment doesn’t know. They have everyone’s credit card purchase info, 1,000 rounds of 223 ordered, you are assumed to have an AR. Same for a barrel, fire control group, etc.
Factory lowers can b bought for $39 now, no need for all the cloak and dagger.
True, lowers are dirt cheap.
Unless you make a habit of only buying with cash at gun shows. Even if you order online, if you have ONE registered AR-15, how can they know how many UNREGISTERED AR-15s you have?
