Any one want to help with a project im working on?
I don't know how to figure out specs for springs needed .

I've got a license of the spring design suite from the Spring Manufacturers Institute.
I don't have it installed on my own workstation currently, but can. How cool is your project?
So what spring calculations do you need?
So gas piston then, since you don't have a buffer tube. You need to figure out spring rates to return the bolt and carrier to lockup at the barrel?
Looks like pistol buffers are short with a shortened BCG.
These guys have a mechanism with no buffer:

Sig MCX-way is probably better, because I've no idea how barrel heat will end up affecting spring steel. So what's the total reciprocating mass and length of travel? Is it only 4.1 inches or does it need to be longer for clearances/tolerances?
This thread makes me wonder; has any firearm ever used a progressive recoil spring? They are used in some suspension applications, and I do not remember ever seeing one in a firearm.

Also, what's the spring/tube diameter?
