Reassembly

1. Attach the gas tube assembly and upper handguard by holding the pistol by the forward

portion of the receiver with your left hand, and with your right hand install the front end of the

gas tube on the gas block. Check to make sure that the flat face on the gas tube lock is still

vertical, then align the gas tube end with its groove in the rear sight base and rotate it

downward until it is fully seated in the rear sight base. Rotate the gas tube lock arm downward

until it is seated in the recess on the right side of the rear sight base to lock the gas tube

assembly in place.

2. Install the bolt back in the bolt carrier by first holding the bolt carrier upside down in your left

hand with the gas piston facing away from you. Then take the bolt in your right hand with the

bolt face facing away from you and the guide lug facing upward. Insert the bolt shaft into the

guide hole on the bolt carrier and bring the bolt fully rearward. Align the bolt guide lug with

the channel in the bolt carrier and rotate the bolt to the left. Once the guide lug has entered

the channel in the bolt carrier continue to rotate until the bolt has moved forward as far as

possible. (See Illustration #16.)

3. Make sure that the hammer is cocked (locked underneath the sear) before attempting to install

the bolt carrier.

4. Install the bolt carrier and bolt back onto the receiver by holding the forward portion of the

receiver with your left hand and with your right hand take the bolt and bolt carrier as shown

in Illustration #17 ensuring that your thumb is placed on the back of the bolt to hold it fully

forward. Insert the gas piston into the gas tube end and align the back face of the bolt carrier

with the inside face of the back plate of the receiver. Using the heel of your right hand, depress

the bolt carrier against the pressure from the hammer spring so that the guide grooves on the

sides of the bolt carrier are aligned with the rails on the receiver and move the bolt carrier to

its fully forward position. (See Illustrations #17 - #19.)

8. Remove the gas tube assembly and upper handguard from the pistol by holding the forward

portion of the receiver with your left hand and rotating the gas tube lock arm upward until the

flat face of the gas tube lock is vertical with your right hand. Then, lift the gas tube end

vertically out of its groove in the rear sight base and remove the front end of the gas tube

from the gas block.
