Geissele Super ACR Trigger for Bushmaster ACR 05-240

Geissele Super ACR Trigger for Bushmaster ACR 05-240 is built for use with the Bushmaster ACR rifle, giving that platform a genuine two-stage trigger upgrade over its factory unit.

This Geissele ACR trigger is non-adjustable, with a total pull weight of 4.25-4.75 lbs. It offers improved ACR weapon system performance with a feel similar to Geissele's Super Semi-Automatic trigger — light enough for precise shots, forgiving enough for close-quarters use.

One important install note: this trigger does not come with a Geissele hammer spring. The original Bushmaster hammer spring must be used with this trigger, and all Bushmaster removal and installation procedures should be followed exactly when swapping it in.

Key Features:

• Two-stage design, non-adjustable
• Total pull weight: 4.25-4.75 lbs
• Built specifically for Bushmaster ACR platform
• Feel similar to Geissele's Super Semi-Automatic trigger
• Requires original Bushmaster hammer spring (not included)

This Bushmaster ACR trigger upgrade brings Geissele's trigger feel to a platform that doesn't often get this kind of dedicated aftermarket support.
