Unfortunately, I've already painted this one to match the body.

Can someone explain how refinishing the flatline is supposed to increase velocity?

If all they are doing is sand blasting it, i can foobar that here.

I'll start by soaking it in hot water

Hmmm, I may have just found my issue, (fingers crossed) I'm still soaking it right now but when I was taking it off, I'm not sure the barrel was seated into the threaded barrel back all the way. Which would explain why it shot fine with the stock barrel and not with the flatline

Looking into the barrel, it still looks like it has been sand blasted

Close enough, got it to 240 and there is still a little adjustment in the velocity screw

The inside of that flatline should feel actually abrasive to the touch. On that thread linked to earlier I was actually really surprised at the difference between before and after. The pictures didn't do it justice.

I'm not sure how that could affect velocity though, aside from the finish taking up like an additional micron of space in the barrel and giving you a little tighter bore haha. It will definitely affect how fast that ball is spinning when it leaves your barrel though.

Sounds like you got it more or less figured out though. One other question: how old is the marker and are you shooting air or co2? Have you tried the other gas?

240 + some adjustment space might also be close enough that fixing that small valve leak might make a difference.

Hpa, 800 psi. I don't have co2.

I'm pretty sure the biggest problem was the barrel not being seated all the way in the adaptor

I'm wondering if my valve spring was a little stiff but ya, I'm not worrying about it

Also the guy who was wanting to buy it I think it's now ghosting me so, whatevs
