Frequently asked questions

What makes the BFSIII binary trigger different from a standard trigger?

The BFSIII fires on both trigger pull and release, effectively doubling your rate of fire. It remains semi-automatic—each round requires a separate finger motion, either pulling or releasing.

Is the 16-inch barrel suitable for accuracy at distance?

Yes. The midlength gas system with a 16-inch barrel delivers solid velocity in 5.56 NATO and maintains accuracy at typical rifle distances. Optics-ready configuration allows you to mount your preferred sight system.

What is an FFL transfer in California?

An FFL transfer is when a federally-licensed dealer like TacticCAL receives a firearm shipped from another seller and processes California's required DROS paperwork to legally transfer it to you. Find gun store Richmond at TacticCAL.
