Here is a linkfor you to keep yourself informed and on the right side of the law. If you don’t want to deal with the headache of changing laws, get an NFA trust and buy a sbr and a suppressor. This post will still help with assembling and sourcing parts for any AR platform build. So we are clear, an AR pistol is not a rifle, disclaimer over.
Deciding on the length of the barrel was not easy, this pistol needed to be easy to maneuver and 100% reliable. If you are having this same issue do this: IGNORE THE INTERNET and anyone who doesn’t even gun. These people will just spew half truths from YouTube videos they’ve seen and act like they know what they are talking about. Do what I did and call someone who actually makes barrels and shoots these guns. I called Ballistic Advantage and explained my situation to the super friendly guy there and without hesitation he said, “You know what, let me get Clint to help you, he makes the barrels.” Again name one company who will do that. Clint got right on the phone, he was genuinely engaged and interested in my build and really gave me that warm and fuzzy of what customer service really is. I told Clint I wanted a 100% reliable pistol that I could trust with my life. Clint asked me a series of questions ranging from what muzzle device, BCG, and buffer weight I planned to use. He made a few suggestions on what he typically does to make his pistols run without issue. We agreed to go with their 10.3” barrel. He then mentioned that he has a line of barrels called the Hanson Series. This barrel profile was developed by Clint Hanson and this is a brief description from their page on exactly what a Hanson series barrel is.
“The Hanson Profile, just like the quality and accuracy you have come to expect from BA, the Hanson continues this pattern. This barrel is essentially shoulder-less, symmetrically limiting barrel “whip”. The Hanson is designed to return to its home position sooner than other barrels which are beneficial for follow up shots at a high rate of fire or full auto fire. It has lightweight feel without the lightweight limitations. It is truly ideal for what an AR-15 is meant to do.”
I finished the assembly of the upper and all but sprinted to the range to test fire and zero the pistol. After having three fail to eject malfunctions and overall shitty function I went home crushed. This pistol that I spent this time and effort into was a dud. The next morning I called Clint at BA for some help and he dropped what he was doing to help me diagnose the issue. I explained the issues that I was having and we were able to come to the conclusion that the charging handle I was using was the culprit. It was warped and the finished was terrible. The charging handle was binding up the operation of the pistol, so I swapped the junk one out for a BCM Gunfighter mod 3. I went to the range the following day and wouldn’t you know it, the pistol ran like a sewing machine. I put 300 malfunction free rounds through the pistol and held groups far better than I was expecting for this length barrel.

The only malfunction I had was due to a muddy magazine that created a double feed. We put approximately 600 rounds through the pistol that day and it ran flawlessly in the mud and rain.
Here is the link to the YouTube video I made from the course.
Something to consider if you plan to build a pistol; a single point sling is key for maintaining a nice cheek weld while keeping that brace clear of your shoulder. All you need to do is push the pistol out and the sling tension will be more than enough to have a nice tight cheek weld.
