http://Airgunsworld.com We did a few mods on the Gamo PT85 Socom air pistol to get around the inaccuracies of the stock Quad Accessory Rail that a red dot sight mounts to. The Quad Accessory Rail actually moves around to much to make the air pistol accurate at all after sighting it in. We have a work around that really improved the performance of the shot group accuracies.
