This past spring my ES was very wide on this gun and it was suggested to me to replace the compression tube so i did.
Initial test shots looked only slightly better so I set it aside until this week. After sitting 6 months or so I wondered what it would do. I fired 1 shot to test the speed and started recording the shots after that.
75 degrees in the basement during the test. I am QUITE happy with the results. It was mentioned that sitting for so long the new seal likely conformed to the shape of the compression chamber. Whatever it was, I am happy.
