I – Disassembly/Assembly Guide

A. Stock

Your Bar10 rifle comes with an allen keys specially for the two bottom screws. Remove this 2 allen screw then loosen the screw under the trigger guard with the use of a Philips screw driver.

Carefully detach the upper portion of the rifle once the two allen screw was removed/

Watch for the magazine catch on the stock as it may flew off. The spring is so small and exact replacement is hard to find.


Loosen the crew under the receiver(fig3), then twist the outer barrel counter clock wise to detach it from the receiver.

C. . Hop –Up System

Unscrew the Hop Up holder from the Outer Barrel then detach the hop up adjuster lever. You may now pull out the barrel and hop up assembly.

Open the hop up housing,

Remove the 3 screws that hold the Hop up adjuster

Lift the half part of the housing carefully while holding the barrel.

EdGi Ported Tight Bull Barrel

Notice the light passing through from the upper port to the lower port hole.

Install the stock hop up rubber then seal it with a Teflon tape. Wash first the rubber with soap to remove oil and grease. Aftermarket Hop up rubber may not need teflon sealing. You may also purchase an Anti blow by ring as a seal instead of Teflon tafe.

Observe for the position of the rubber lock that goes inside the slot of the other half of the hop up housing.

Before closing the Hop assembly, make sure that the notch of the hop up rubber is properly seated in the slot on the hop up housing.

An EdGi barrel with a hop up set to Zero.

Install everything back inside the outer barrel but remover first the End cap so that it won't damage the crowning of the barrel.
The stock plastic barrel spacer inner hole were small for the new EdGI barrel. You may enlarge the hole with the use of a round file or a 220 grit rolled sand paper.


Open your Cylinder first and remove all the internal parts ; Piston, Spring, Spring Guide before removing the trigger assembly. Removing the spring guide stopper first will cause a damage on its upper lip/dimple that may lead to slam firing, harder bolt return.

I would like to buy the edgi kit, but only custom parts. For my science fair project I am going to study components to the speed and accuracy of the JG Bar 10. I'm low on money and have to buy it myself so I need to cut the price down a bit.
