Building your own 300 Blackout AR is a tremendous amount of fun! Getting into your first or even your second build can be intimidating and even a seasoned builder runs into questions. At 300 Blackout Upper we want to equip you with all the parts and information you need to complete your build. However, we by no means are providing legal advice or counsel and you should always contact your local ATF officials if there are any questions. 

We often get a lot of questions around the legalities of the 80% lower and AR-15 Pistol specifically, so we wanted to take a few moments to provide you with some guidance.
