Modular insertion trigger method and apparatus
First Claim
1. A trigger assembly adapted to be fitted to the lower receiver of a firearm having a central chamber region having a lower surface, the trigger assembly comprising:
- a) a housing having a forward and rearward regions and first and second lateral walls and a base portion providing an upper surface,b) a locking system having an extendable member that is adapted to engage the lower receiver to minimize movement between the housing and the lower receiver,c) a hammer pivotally connected to the housing in the forward region of the housing, the hammer having a hammer disconnector sear surface,d) a trigger pivotally connected to the housing, the trigger having a trigger sear surface located in a forward region,e) a trigger over travel adjustment system having an adjustment member with a lower surface adapted to engage the upper surface of the housing to limit the range of rotational travel of the trigger in a first rotational direction,f) a trigger take up adjustment system having an adjustment member with a lower surface that is adapted to engage the upper surface of the housing to limit the amount of rotation of the trigger in a second rotational direction, the trigger further having a safety engagement surface,g) a safety system comprising a laterally extending member and an adjustable member having an adjustment surface that is adapted to reposition with respect to the laterally extending member, the adjustment surface adapted to engage the safety engagement surface of the trigger to limit rotation in the first rotational direction when the safety system is activated.

Abstract
A trigger assembly comprising a housing adapted to mount a trigger, hammer and sear therein. The housing has an adjustment feature adapted to fixedly mount the housing within the trigger chamber portion of the firearm. The trigger assembly is particularly conducive for an AR-15 type rifle and the various sear engagement surfaces are adapted to be adjustable irrespective of the various dimensions and tolerances of the underlying firearm. A safety system is employed that adjustably allows proper engagement of the trigger tail to properly engage and disengage the safety mechanism.
