You can get your kit with a choice of either of two Geissele AR-15 Enhanced Triggers, both available ONLY from Brownells:
The B-G2S-E Geissele 2 Stage Enhanced Trigger has a two-stage pull that provides superior control and helps accuracy while maintaining the robustness and reliability Geissele triggers are famous for. The B-G2S-E has a smooth, light 1st stage take up of 2.3 lbs. and a crisp, candy-cane-like 2nd stage break at 1.2 lbs. The B-G2S-E is ideal for use in precision rifles where accuracy and reliability are both critical.
The B-GC Geissele Competition Trigger was developed to produce a short, relatively light single-stage pull with a short, quick reset that are ideal for 3 Gun competition and recreational target shooting. Two trigger springs are included so the B-GC can be set up with a 3.2 lb. or 4 lb. pull. The B-GC trigger is not recommended for benchrest shooting or shooting that requires small groups. It is designed for competition involving rapid target engagement.
