brass impact regulator piston

@mubhaur ?

Just short of 1mm

The main thing I'm looking to get from a brass piston is reduced set point shift due to temperature changes. It's very noticable on the plastic piston. 70deg F to 40 deg F is around 10 bar change on my M3. Other than that issue, the plastic piston works great and it has the advantage of not needing a separate sealing surface material.

I wonder if they will offer the brass piston as a "200 bar upgrade package" that includes a full stack of 0.6mm belleville washers. Huma uses that for their 200 bar setup. The default AMP stack is 50/50 0.5mm and 0.6mm washers. I suspect 200 bar may be pushing the hybrid spring stack a bit too far.

Which dimensions are you taking about?

I just installed 2 of the brass pistons in a M3 had to take .030 thousandths off the derlin otherwise the adjuster sticks out way to far

They will also fit in the mk2 with the amp reg

after a few months of use and testing, does the new brass piston work well? I have two impact issue towards velocity variations in the first few shots, and the 2 reg which doesn't have constant pressure.
if your opinion is positive I order two brass pistons from fx to try to fix these problems

Had same problems I think the plastic piston has problems with the washers getting hung up on it switched out the pistons and it helped

Could you give me the dimensions of the piston please. I cannot find it anywhere. Thank you
