Frequently asked questions

What is a binary trigger and how does it work?

A binary trigger fires once on the press and once on the release of the trigger. This doubles your rate of fire compared to a standard trigger, without converting the rifle to a fully automatic weapon.

Is the Mach1 handguard compatible with standard AR accessories?

Yes, the Mach1 handguard uses Picatinny rail sections and standard mounting points, allowing you to attach lights, lasers, and other common AR-platform accessories.

Can I transfer ammo through an FFL in Sunnyvale?

Yes — TacticCAL processes ammunition shipments from online sellers under California's ammunition eligibility check requirements. TacticCAL is your FFL dealer Mountain View in the Bay Area.
