This will hold me over until the longer .177 barrel goes on.
here is "how to" make easy external SSG for 2240.
sharpshooter what is the forearm on your 2240?
Okay, I decided I wanted to ensure the spring guide had no threads to snag the coils of the spring so I took a piece of 3/16" cold rolled steel rod and tapped both ends to #10-32. I then turned down a standard hex nut to an OD of 0.30" to capture the spring. The parts laid out:Dry fitted together:And lastly, on the gun:I played around just a bit with the gap adjustment until the velocity came down from 510fps to 460fps. It was noticeably quieter and the braaaap sound was either much improved or gone altogether. But I decided I wanted to keep it tuned to around 500fps so I reduced the gap until it did. The resulting gap is 0.030". It's still pretty loud which is to be expected for keeping it near its max velocity, but the bounce is improved so that will save air.Thanks again for the link!
