The Trigger Mechanism Housing (TMH)

Fully withdraw the TMH rear locking pin, then push it back approximately 5mm (a distinct click should be heard) this retains the recoil rod assembly whilst the TMH is being removed. Fully withdraw the front locking pin.

Separate the TMH from the body by pulling the butt upwards, cup hand over the end of the body to ensure the recoil rod assembly does not spring out.

The Recoil Rod Assembly bolt assembly and Cocking Handle.

Place the hand over the rear of the recoil rod assembly, fully withdraw the rear TMH locking pin and remove the recoil rod assembly.

Slide the cocking handle fully to the rear, disengage from the bolt carrier, continue sliding the bolt carrier to the rear and remove from the body.

The Gas System

Ensure the weapon is level, upright and open the top cover.

Push the piston to the rear, move out of alignment and remove.

Remove the gas cylinder. Point out gas settings N=Normal, E= Excess, O=Off.

Depress the plunger on the front of the plug ensuring it is not in the 6 or 12 o’clock position and remove. (11) ASSEMBLING Carefully feed the spring end of the piston into the hole above the barrel extension

Insert the plug into the block and depress the plunger ensuring it is not in the 6 or 12 o’clock position and push through. Rotate the plug until the plunger is in the N position.

Fit the cylinder back on the gas plug knurled end away from the gas block.

Then align and engage the piston into the cylinder. Then close the top cover.

Ensure the bolt is fully forward in the carrier, insert the bolt carrier into the body of the weapon to enable the cocking handle to be inserted into the bolt carrier. Move the bolt carrier and cocking handle fully forward.

With the rear TMH locking pin fully withdrawn insert the recoil rod assembly into the body until the end of the assembly is flush with the end of the body.

Push the rear TMH locking pin in 5 mm to engage the recoil rod assembly, (a distinct click should be heard)

Check the TMH front locking pin is fully withdrawn, then fit the TMH by inserting the front end into the catch behind the hand guard. Raise the back of the TMH and press the body and the TMH together. Fully engage the TMH rear and then front locking pins.
