Troubleshooting Guide

When you start troubleshooting it's important to go at it with an open mind. You want to consider all parts to ensure the potential problem isn’t accidentally overlooked. It’s important to keep in mind the potential for tolerance stack-up. It is possible for all parts to be within proper specifications but when stacked together, the whole unit is out of tolerance (due to some parts falling within tolerance minimums and others within tolerance maximums). For this reason, we recommend a certified armorer or gunsmith confirm the completed unit is within proper/safe tolerance. At BA we strive to hold extremely consistent, optimum dimensions to avoid any tolerance stack-up issues.
