Anyone using Greg Davis' reservoir tube extension?

Bought, paid for, received and working fine on the rifle.

... and then taken off within two days and re-sold and the new owner says it is holding pressure fine.

Why the removal and sale? Because it was on my wifes Marauder and she did not like how it looked. I thought it looked fine but it is her rifle and she did not like how it looked... so it went.

Sealed well and was easy to install. Looked nice to me and made a nice addition, but it was not my rifle. Am sure some of you understand.
