DIY MASK Air Brake Piston Head
by: zx101
The MASK piston head is the easiest piston head around to convert into an air brake piston head for AEG sniper set up. The MASK piston head has a built in crater designed to where the sorbo tablet is sited and even a long screw can just simply pass through without any drilling a hole in the piston head . This is perfect for air brake modification. But before we proceed to the main objective of this topic. Here are some facts about the air brake piston head.
Q. What is air brake piston head?
A. Air brake piston head is commonly use in Tokyo Marui VSR10 sniper rifle. This piston head has a long shaft facing forward to the cylinder head.

Q. What is the purpose of air brake?
A. Air brake is designed to increase drag during the forward motion of the piston to the cylinder head thus listen the impact when it collide to the cylinder head and generally produces a silent sound during the actual firing with bbs.
*This is best for sniper rifle and semi auto AEG for silent and unnoticeable operation in the field.
* Sniper gun should be quite as much as possible so that the enemy wouldn't notice where the bbs came from.
Q. If there is an air drag, then there must be a loss of muzzle velocity?
A. Yes, there is a minor loss of FPS, because the speed of forwarding piston is being block by the air drag.
Q. Can I use the air brake piston head in a high speed set up AEG?
A. Yes, as long as the air brake shaft has enough tolerance inside the cylinder head's hole. But I can not guarantee for a best result in high speed set up.
* This modification requires high understanding in AEG mechbox .
* For beginners, contact your nearest gun doctor before doing this modification.
Steps on converting MASK into an air brake piston head.

materials needed:
acryl rod, long screw ( 3 x 30), glue, drill/drill bit, sand paper #300 #1000, locktite and thin plastic/wood rod.
long screw and 6mm acryl rod
Step 1- Remove the sorbo tablet in the piston head. Use any wood or plastic thin rod to remove the sorbo tablet ( Do not use a sharp or pointed rod). Gently insert the rod from the back side of the piston head and push the sorbo tablet out from the piston head crater . Be careful not to damage the piston head thread.

Step 2- After removing the sorbo tablet, make a center hole on it by drilling or using a hole puncher.
Step 3- Cut the 6mm acryl rod and start sanding it. Try to insert inside the cylinder head's hole once in a while to check the right diameter of the acryl rod. The acryl rod must move freely inside the cylinder head's hole. Do not over sand the acryl rod.
Step 4- Use a 3mm drill bit and drill the center of the rod. Approximately 6mm in depth.
- After sanding and shaping the rod. This is the actual air brake shaft.
- Air brake shaft must move freely inside the cylinder head's hole. It must have enough tolerance to avoid jamming and any trouble in the future.

Step 5- Place the piston head in the piston, place the bearing and lock with the long screw. Do not over tight the screw.
Step 6- Apply glue or adhesive in the piston head crater.
Step 7- Insert the screw in the sorbo tablet . Press the sorbo tablet inside the crater.
Step 8- Apply small amount of oil inside the air brake shaft hole.
Step 9- Insert the long screw to the air brake shaft. Turn clockwise at the same time push the screw inside(same of process of inserting a screw/bolt in the knot). Do it continuously until the air brake shaft touches the bottom of the piston head crater . Make it sure that the air brake shaft is well sited.

I'm going to install this in my King Arms DMR sniper with pdi 210% spring.
Please stay tuned for the test result.

Basic Installation Guide of Sorbo Pad
by: Ramon Lim aka zx101 of Fil Airsoft
*Gearbox disassembly is required. For beginners, contact your nearest gunsmith for proper installation.
Take out the cylinder head from the cylinder.
Remove the stock rubber damper, pry it out using a flat screwdriver .
Stock rubber damper is now completely removed.
Most adhesive does not stick well on the oily surface. So remove the excess oil in the cylinder head. Wash the cylinder head w/ dish washing soap. Using a brush will also make the work cleaner and faster. 
After cleaning/washing. Apply small amount of alcohol in the cylinder head surface, wipe it with damp cloth and let it dry.
Strip the adhesive’s outer skin and put the sorbo pad in the cylinder head.
Make it sure that the sorbo pad is securely installed. Press the cylinder head against the flat surface.
Sorbo pad is now completely installed. A.R.S. sorbo pad fits perfectly.
My set up.
systema m130 spring
systema torque up gear
prometheus spring guide
Prometheus hard piston
systema pom piston head w/ bearing
systema area 1K 6mm metal bushing
element sector chip
modify type 0 cylinder
509 mm prometheus 6.03 inner barrel
TM eg1000 motor long
TM stock cylinder head with A.R.S. sorbo pad
After placing all the upgrade parts and tested my gun,
I am very impressed with the A.R.S. sorbo pad, put one in my custom TM M16 VN and it rocks, huge difference in sound, quieter, reliable and cheap!.
How to use MASK piston head without bearing
by: Ramon Lim aka zx101 of Fil Airsoft
I just bought today a MASK piston head without bearing and ARS sorbo pad for my G&P AK47.
Since I have an used bearing from my old systema duracon piston head im going to use this with the MASK piston head without bearing.
I just bought today a MASK piston head without bearing and ARS sorbo pad for my G&P AK47.
Since I have an used bearing from my old systema duracon piston head im going to use this with the MASK piston head without bearing.
Systema's guide bushing, flat head screw and bearing are perfectly fit to the MASK piston head. After transfering the parts. MASK now looks like a bad boy.
_______________________________________________________
Update in my M4A1
In my G&P M4 the original fps was 420 using PDI 190% in stock inner barrel.when I installed the MASK piston head and ARS sorbo pad. My fps went down to 405 fps
Since Tirador ( ARS owner ) even admitted that the downside of the MASK is the O-ring.
I changed the silicone O-ring to black TM O-ring, installed a madbull 6.03 tight bore barrel and did a cheese mod in my piston body. Now my FPS increased and consistent at 450fps.
here is the pic of my ARS MASK piston head and cheese mod of my deepfire titanium full teeth piston body.
I run with 11.1V lipoly through several thousand rounds and MASK is still holding up so far.
