So I bought a "complete upper" about a year ago and put it in the safe. I just took it to the range and the student casings wouldn't extract. Didn't take long to figure out there was no ejector pin or spring in the bolt. So I ordered the pin from hkp and the spring from HK haus. Well the spring is longer and seems to have more tension than the one I compared from a different bolt. Jess from HK haus says it came straight from HK and should work but I can't get it in. On top of that, I can't even get the shorter one back in so I'm looking for opinions/tips.
