DEFUNDR Trigger

DEFUNDR Trigger – MPA Defender

Current Status: In Production

Estimated Lead Time: 3–4 Weeks

The DEFUNDR Trigger is designed exclusively for the full-size MPA Defender 30T platform and is compatible with both side-charging and top-charging models.

Construction

Hammer manufactured from heat-treated 4140 steel

Hammer finished with a durable DLC (Diamond-Like Carbon) coating

Out-of-battery lockout machined from 6061 aluminum anodized red

Reset trip components manufactured from 304 stainless steel

Function

The DEFUNDR Trigger utilizes a rear-stroke reset system that mechanically resets the trigger during the bolt’s rearward travel. The trigger remains locked out and unable to release the hammer until the bolt has fully returned to battery.

This integrated out-of-battery lockout helps ensure proper timing and prevents hammer release before the firearm is fully in battery.
