Re: Armalite AR-10 Super SASS gas system help?
Three bastard rings on each grove. If you can do that you are home free.
Lube the assembly and start it into the block. Carefully ensuring the gas rings are clocked at different possitions. Make sure you do not allow them to overlap on assembly.
Once you get the valve and rings on, slip the knob over the shaft with the spring and detent ball in place. Use a small punch to hold the knob in position and insert the roll pin from the oposite side.
Run the roll pin slowly and allow the punch to come out. After that all you have to do is insert the gas tube into the nut, and screw that assembly onto the valve.
Install the assembly on the rifle, align, torque down.
Oh, almost forgot a step. If you are like me, once you get the tube and nut secure and go to install it, cuss like a sailer because it is too big to fit the forearm you have and kick yourself for not buying the SASS rail as well!
Hope this helps a little anyway.
