FIGURE 18 Replace action bars. FIGURE 19 Replace bolt release spring. 3 Screw on and tighten the gas cylinder screw cap on the front of the gas cylinder. 4 Replace the action bars: Place the bolt in its forward position. It is helpful to release the magazine floorplate to the open position so you can check alignment of the action bars on the bolt. Place the projecting section of each action bar carefully in its corresponding slot in the bolt before the action bar is fit onto the inertia piece. (See Figure 18.) The action bars are interchangeable. It may be necessary to pull the inertia piece slightly rearward to engage the action bars. 5 Replace the bolt release spring and bolt release lever and pin: Close the magazine floorplate and keep the bolt in its forward position. Replace the bolt release spring. (See Figure 19.) Replace the bolt release lever. Line the hole in the bolt release lever with the hole in the receiver and insert the bolt release pin. Lock the bolt release spring onto the bolt release lever. 21
