When the Bushmaster ACR was released, everyone expected it to take over the AR-15 market with aftermarket parts and accessories, but sadly no companies stepped up to the plate. Geissele Automatics has decided to change that by increasing their line of high-quality triggers to include the ACR pattern of rifles hitting yet another home run. The Super ACR two stage trigger comes with all the features you would expect like an extremely smooth travel and short, tactile reset that resembles the popular Super Semi-Automatic AR-15 trigger. It also retains all the reliability and safety of the combat proven trigger system that ensures function during high stress situations. This trigger is recommended for law enforcement, home defense, and hunting applications. The Super ACR trigger eliminates the gritty and heavy feel of the standard Bushmaster trigger and will give you a sense of satisfaction for jumping on the ACR hype train that crashed a little too soon.

  • Uses Mil-Spec .154” pins for installation
  • Works with all Bushmaster ACR DMR, SBR, and Enhanced variants
  • Inspired by the same trigger used by U.S. Special Operations groups
  • Smooth 4.5lb two stage trigger pull
  • EDM wire cut from heavy duty tool steel
  • Great for precision shooting and reliable for home defense/duty use

Note: Trigger pull weights are approximate and may vary slightly between rifles.

Note 2: Follow all Busmaster removal and installations to install this trigger. This trigger does not come with a Geissele hammer spring. The original Bushmaster hammer spring must be used with this trigger.

The Bushmaster ACR may not have the aftermarket support like the AR-15, but it is still an incredibly well-made and effective rifle system that only needs one improvement; the trigger. The Geissele Super ACR trigger aims to improve upon it with a 2.5lb first stage and 2lb second stage with a crisp, consistent break. The curved trigger bow offers familiarity with M4 style rifles and helps to keep your finger placement consistent when shooting multiple rounds. The installation process is a little lengthier than AR-15 trigger swaps, however, it uses standard Mil-Spec .154” trigger pins for compatibility.

Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.
