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.
