SOLD Thank-you AGN
Airgun Lab Double Tube Kit for Prod/1720T w/Shotgun Forearm/Rail
This is for the kit and grip. Gun is not included.
Increases the air capacity of your Prod/1720T to slightly more that double. Double your shot count. This was purchased new from Airgun Labs (Lloyd Sykes).
This is the steel tube version.
Installation Instructions
The shotgun foregrip has two inner sleeves and slides on the double tube. It has one mounting screw that goes into the into threaded hole on the tube. The rail butts against the grip and clamps to the tube.
Note 1: When I dis-assembled gun, air pressure was at 1000psi. I did not isolate the leak to the gun or double tube. I included the O-rings that I had left from the kit, All O-ring sizes and durometers are listed on the card. There are some small scratches in the finish on the tube from where the barrel band installs and foregrip/rail.
Note 2: If you have a 2021 manufactured Prod/1720T, you will need the old style gauge block with 1/8" NPT threads. The new have 1/8" parallel threads. I will include the gauge block, if that is what you have.
Asking Price is $185 Papal F&F or you pay fees. Shipping/Insurance included for CONTUS only.
