This B-GC Trigger from Geissele Automatics is a match-grade, single-stage drop-in trigger for the AR-15. The trigger releases the hammer to fire the round, and a single-stage design breaks with one continuous pull rather than a separate take-up stage, which competition shooters often prefer for a lighter, more consistent pull weight than a mil-spec trigger (Geissele Automatics part no. 05-275).

Key Specifications

• Functions as the trigger, releasing the hammer to fire the round.
• Built as a single-stage trigger, breaking with one continuous pull rather than a take-up stage.
• Rated as a match grade fire control group.
• Installs as a drop-in unit without additional gunsmithing.
• Sold as a small-parts kit, not a complete firearm — it’s classified as a firearm accessory, so no FFL transfer is required to buy it.
