Ya, actually, in comparison KM TN cylinders aren't THAT expensive...
Barely 26 bux, and the modify one for sale by juggz is around 15... 11 bux plus like 1 usd on average of shipping cuz of my huge ass order from ehobby.

Hm, now that you put it that way, i'm debating between prometheus inner barrel at 407mm or KM tn coated at 407 mm. haha
Thing is ehobby and redwolf both don't have the 400-590 cyilinders in stock atm, I doubt putting a 400 would be good for 407.

The G&P polycetal has 3 metal teeth... lemme check the details:
"In general, polyacetal is not quite as strong as polycarbonate but has significantly more toughness. Additionally, polyacetal has good inherent surface lubricity and high fatigue strength. These factors should in theory combine to make a great reinforced piston. G&P also departs from the traditional 1 metal tooth design by providing 3 metal teeth for increased strength. Several "cut-outs" are molded into the top of the piston, creating a backbone-like structure which may increase strength while reducing weight. Cursory examination reveals some visible molding lines and a smooth molded surface. The 3 metal teeth have a rough shiny coating, similar to Deepfire teeth.

Piston: G&P Polyacetal High Pressure Piston
Weight: 0.5oz
Piston Material: polyacetal
Metal Teeth: 3
Average Barcol Hardness (piston): 12.9
Average Barcol Hardness (tooth): 84.1
Tapered Lip: yes, slightly
Distinguishing Feature: 3 metal teeth, molded backbone"

After the 1k round testing on M140:
"The G&P polyacetal piston performed quite well well, showing miniscule deformation due to contact with the first sector gear tooth. The remainder of the teeth are practically brand new conditon, with very little evidence of any visible wear."

Hm, juggz also has a 7 titanium teeth modify piston with the 2nd tooth removed, costs 15 bux more than 1 tooth, no teeth removed. I guess this would help a bit but isn't the proper way of fixing AOE, by finding out which tooth the piston is at when the sector gear lined up to it is almost 90degrees, or at least the line between taht tooth and sector tooth to be 90 degrees and cut a slant from that tooth's top to near the bottom of the 2nd?

And do you think on low rof guns it would be smart to short stroke like one tooth too? (not to achieve high rof)
