Installing lower to receiver

[Joseph Scott 0]

When installing the lower to the receiver, be sure the little flat end of the mag door pin is turned to fit in the recess on face of stock. Also if you have a bolt catch in your gun, you need to depress the mag door and follower to allow the catch to float while you install the rear pin. If not, the follower puts pressure on the catch and throws it out of alignment for the pin. Sometimes you might need to loosen the screw under the safety and in the stock recess to allow the hammer block to shift slightly. Retighten after installing pin.
