What is BA Hanson?

The BA Hanson Series exemplifies the quality and accuracy you have come to expect from Ballistic Advantage. BA Hanson Profile barrels feature a shoulder-less design, symmetrically limiting barrel “whip” and allowing the barrel too quickly return to its home position. This is extremely beneficial for follow up shots at a high rate of fire or full auto fire. Lightweight feel without the lightweight limitations, it is truly ideal for how an AR-15 is designed to perform.

Can I shoot a .223 round out of a 5.56 barrel?

What is difference in Pistol, Carbine, Mid and Rifle length barrels?

This is a length that refers to the gas system on your AR 15. Starting with Pistol the shortest, it measures 3.75 inches. Next, is Carbine at 6.75 inches, Mid length measuring 8.75 inches and finally Rifle that is either 11.35 inches or 12.15 inches depending on the caliber.


What rail length do I need to comply with your standard length barrels?

This is a twofold answer: Do you have a front sight base? If you do, and you have purchased a M4 carbine then you should have a 7” rail. If you have a Mid length barrel then you should have a 9” rail.

If your barrel does not have a front sight base then it is a personal preference depending on how much barrel you like extending out from your rail. Typically, you subtract a ½” at the front and a ½” at the rear then, subtract how much barrel you want to have protruding past your rail.


Will Ballistic Advantage cut and rethread my barrel to a custom length?

This service is not available but, we do entertain custom barrel orders in lot runs of 100 or more.


What is a free floated barrel?

This is a term used to describe a build where the barrel has no contact to any part other than the upper receiver. This includes the rail and the gas block but the gas tube connection is ignored in this definition.

Will my 5.45 bolt work with a BA barrel?

Headspace correct for BA barrel:
- Smith & Wesson
- Spike’s Tactical
- Adam’s Arms

Headspace NOT correct for BA barrel:
- Model 1 Sales

Will my BA 5.45 barrel work with my piston kit?

Our barrels have been optimized for direct impingement. A piston will work with BA barrels, but occasionally some customers have found the need to enlarge the gas port. If this is the case, the complete upper with piston can be shipped to us and we can increase the port for proper function for a $50 shop charge (customer to pay for shipping). If you are able to increase the port yourself we recommend the smallest increments possible.

What 5.45 ammo works with your barrel?

The only ammo that we have found to have function problems is Wolf 5.45×39 WPA Polyformance 55 grain HP ammo. The spec of this round will not match the spec of our chamber so we strongly recommend you do not use it.
