• The front trigger pin is shorter than the rear trigger pin.

• Insert tapered ends of trigger pins first.

7. Using finger pressure, squeeze the trigger (15) together vertically so that the holes in the sear, trigger housing assembly

(4), and receiver (2) are aligned. From the left side of receiver, insert the front trigger pin (6) (tapered end first) ensuring

it is flush with the edge of the bolt stop slot on the receiver. Insert the rear trigger pin (1) (taper end first), ensuring it is

flush with or slightly below the edge of the bolt stop slot on the receiver.

8. Place bolt stop spring (5) over the rear of the trigger pin (1) with the short leg of the spring captured against the receiver

(2) in the trigger housing assembly (4) slot. While holding the front leg of the bolt stop spring out of the way, insert the

bolt stop release (3) into the bolt stop slot on the receiver.

9. Ensure that the hole on the bolt stop release (3) is aligned with rear trigger pin (1) hole. Use a 1/8-in. punch and 4-oz

hammer to drive the rear trigger pin through the bolt stop release until it is flush with the outside edge of the bolt stop.
