Hey guys, so I recently got into modding, I did the old coin trick with a blue Maverick that I ordered off eBay, so I've been looking online and am still pretty stumped as all of what I'm looking for is completely gone. Orange Mod Works is also a dead end for me because the only spring upgrade they have listed for the Longstrike (the old N-Strike one, not the new modulus one) is out of stock and it seems to be out of production. I went to a couple of department stores to no avail, so I did some more digging and found https://www.mcmaster.com/ and they seem to have alot of things, including custom springs, however now I am.unsure of how the spring measurements work and what the measurements of the Longstrike's spring even is to begin with. So I was hoping someone could help me?

Thank you in advance!
