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.

Thanks

almost looks like a detent spring to me.

Its slightly wider and much stiffer than a detent spring

Thanks guys. I have ordered a bolt vise, hopefully I can make it work without launching these little pieces all over the place. I did notice the other spring was much stiffer than a typical AR spring I'm just still not sure about the length of the new one

Finally got it installed. After I was able to get it in and compress it one time the length was similar to the other one. Was a major pain in the ass and I hope I don't have to do that again!
