BAR10 ABC Guide - Part2

Sorry folks if it took me a while, as i have to make more Bar10 upgrade parts.

And now, the Cylinder and trigger disassembly procedure and installing the new parts on your Bar10.



As mentioned on the first part of this upgrade guide, the cylinder body must be opened first to remove/uninstall



all of its internal parts. By doing this, you lessen the risk of damaging the internal parts, keeping your rifle workable. This will make sure that the spring guide stopper (SPGS) (The "L" like part on the trigger mechanism) will last longer. The SPGS is the one that keeps the piston and the spring guide centered inside the cylinder. If the dimple hole on the SPGS wears out
due to wrong installation, pushing back the bolt will be difficult, and soon SLAM FIRE..






After removing the internal parts of the cylinder, take off the spring guide stopper.






Sometimes the spring guide stopper drops freely when the cylinder is empty. You use pliers to pull it out if it binds in the reciever.








There are only two Philips screws which holds the trigger system to the receiver. Once loosened, the trigger system can be easily pulled out.






B. Opening the trigger.




Since we need to install the trigger system first into the receiver before the cylinder parts, let' s open it and replace the weak parts - the Trigger Sear and Piston Sear

Remove those screws and see their proper position on the trigger system as you can see in the picture.









Insert a small screw driver inside the spring guide stopper slot to hold the trigger sear and other internal parts intact, then lift the top pair of the trigger housing.



This will ensure that you will not be loosing the tiny parts, such as springs and pins.






You may now remove the sear set from the trigger housing.


Be careful not to loose those springs and pins as replacements are really hard to find.

On top is the Trigger sear, on theleft is the.. trigger sear spring. At the middle is the piston sear and spring, and on the right is the sear pin.


C. EdGI Sear Set installation

These two stock parts the weakest in the rifle because they carry much of the load as the main spring is compressed. As you pull the bolt, the spring compresses and the piston sear catches and holds the piston in place. Once you pull the trigger, the spring decompresses and pushes the piston to build up air pressure. The faster the spring decompresses, greater pressure is generated, equating to higher FPS.



To install the EdGI piston sear, place the piston spring on top of the piston sear, then insert the two inside the trigger sear. The fastest way to do this is by seating the leg of the spring in the trigger sear, then hook the other leg into its slot on the piston sear after the pin is installed.












A properly installed piston sear is ready to catch the piston. Before putting it back to the trigger housing check if the piston sear moves freely upward by pressing it downward, then releasing. 







New Sear Set on the trigger housing ready for assembly.



Don't forget to install the trigger sear spring. Stretch it a bit so that it can push the trigger sear. The new ones are tougher and heavier compared to the stock.

Close everything and install the trigger system in the receiver. Be sure to test the trigger sear before final assembly. Push the trigger sear down as you pull the trigger. It should go downward if you pull the trigger and return to its normal position instantly.



Once the trigger system is installed back to the receiver, check again the piston sear if it still moving freely up and down .


D: Cylinder installation.






Return the cylinder body inside the reciever then install
back the spring guide stopper.









Find a tool that can be inserted into
cylinder head. A small screw driver or longer allen key
will do.
Here, i'm using the allen key that i used on loosening the cylinder head in the cylinder body.










Now install the spring guide with the spring attached then drop the piston inside the cylinder.


Put the cylinder head on top of the piston head, then use the tool to push it inside the cylinder.












Here, I am pushing the piston inside the cylinder with the use of allen key inserted into the cyl head.


Slowly push the piston inside and guide it with your thumb so that it won't scratch into the threads of the cylinder body.


Once the piston is inside, screw in the piston head until it is fully closed. Tighten the cylinder head properly to avoid stripping off the threads. Test fire the kit several times while covering the cylinder head with your thumb for compression testing.

Now, assemble the rifle then do some chronographed shots. Adjust your scope properly for accurate groupings.







Chronograph was taken after 200 rnds of ammo. Thanks to Steven..

Wow very detail instructions, great post!

I was wondering, I just created a new Airsoft site geared toward Airsoft Snipers and airsoft sniper rifles. Would you be willing to do an blogroll link exchange with my site. I think this will help use both since we both enjoy the sport of Airsoft and so are my vistors.

LMK what you think...thanks Matt
