Just a quick thought, considering BB diameters vary, maybe wide bore barrels are better because compared to the bore size the variation of the bb diameter represents a smaller percentage?
Per example: a bb is about 5,95mm +- 0,01mm, so maximum of 0,02mm between bbs. With a 6,01 barrel that's 0,05-0,07 difference. While in a 6,20 barrel the difference it's only 0,24-0,26. So the 0,02mm plays a larger part in a tight bore compared to a wide bore.
That's about the only theory that I can see some logic.

I've never seen any evidence that they are more accurate than tighter bores.

Me neither, I only went back to this topic because I have been eyeing the PDI barrel for VSR for a few years and they gradually changed from 6,01 to 6,08. I just noticed 6,08 very recently, before it was 6,05.
Since it's claimed to be cold hammer forged I don't think they did it to reduce cost, since the tolerance did not change.

that looks literally like polymorph plastic, which you can get much cheaper and reliable on amazon.wyz2285 wrote:Any thoughts on these?

I've used them before for making fake teeth/fangs for halloween costumes and cosplays.

Some people like Lockednloaded and some UK members used it for just such a purpose.Seems cool to make grips or stock...
Good luck! Make sure you sort out your cooling, though at this time of the year you can probably just test it outsidegot a motor and gearbox together for first test as piston pump

yes, cooling could be the issue, it does about 86rpm and I'm trying a 3/4" x 4" cylinder first with a precharge of 20 or so psi. I have a piece of heat sink to strap to the cylinder
I tried a 3/4" x 2" on the bench, with a precharge of 30psi I could hand pump it upto 160psi then it ran out of volume.

It seems like a machine to give satisfaction to the ladies ... I thought that at first sight of the video, but then I understood
Seriously speaking, very good. I have thought about moving a compressor with my stationary bicycle. Every time someone in the family uses it, I open the valve and compress air!
