The BA50 is also one of the simplest 50-caliber rifles to assemble and maintain.

It is equipped with an AAC Cyclops muzzle brake/silencer adapter designed for optimal recoil reduction (and able to accept an AAC Cyclops 50 cal silencer). The BA50 ships with two 10-round magazines, folding steel bipod, and eye and ear protection in a a Storm deployment case.
