Remove the belleville springs and the baffles from the silencer tube taking care to note the order of the baffles (The longest baffle is the blast baffle and has no number marked on it, the 2nd and 3rd baffle in the ARIS silencer is marked with a 2 and 3 accordingly and the M30-A silencer has a 4th baffle marked with the number.
  3. Place all parts into a sonic cleaner for approximately 15 minutes, OR apply a solvent such as BRO PREMIUM CLEANER & SOLVENT to all parts and allow to soak into the carbon. (Heavier carbon build up will result in the need for additional time in the sonic cleaner or repeated treatment with solvents. To avoid this perform regular maintenance on your silencer by cleaning it after each use)
  4. Wipe down all components with a clean rag. Heavier, stuck on carbon may be removed with a wire brush or a razor blade.
  5. Re-Assemble your silencer. From the rear of the silencer place the highest number baffle into the silencer first (Number 4 on the M30-A, Number 3 on the ARIS) with the flat side toward the front end cap. repeat with the next baffle(s), The Longer blast baffle will be the last one inserted.
  6. Twist the blast baffle inside the tube to allow the clocked edges to align and lock the baffles into place. The baffles should turn as a single unit if done properly.
  7. Insert the Belleville Springs. The springs should be installed with the concave side of the first spring facing the blast baffle and the concave side of the 2nd spring facing the rear cap.  [ )( ].
  8. Re-install the rear endcap by threading it onto the tube. Your silencer is now ready to be stored or re-attached to your rifle.
