Standard BA quality & <1moa guarantee
Fit & finish of BA products are comparable to many “high end” manufacturers. I have many BA products, as well parent company Aero Precision parts, and they play perfectly together. No matter if you want a CQB scrapper or a med/long range tack driver, these two have the quality and the attention to detail that will assuredly meet your needs.


Nice barrel for the buck!
So far, the barrel prints nice tight sub inch groups at 100 yds. The gun had issues weak ejecting xm193 and M855 loads and short stroking certain .223 loads but that was apparently due to using a pretty aggressive muzzle brake and poor fit of the gas tube to the gas block (my bad). I have since replaced the muzzle brake with a std bird cage and replaced the gas tube with a higher quality melonite tube. The barrel is light and balanced and obviously well made-spotless finish. BA has been notified of the short stroking issue and are working with me to solve my issue. the barrel shipped right away and was received promptly
