03A3 bolt

[rcathey]

That's what I'm afraid of. The bolt lift is hard and I can barely get the collar and pin on/off. When cocked, all the coils are touching each other. uncompressed length is 4 1/2" but I didn't measure the wire dia.

Not to be insensitive..but if you really believe this is the issue why not just buy a NOS USGI spring? You can buy them all day long on eBay for about 8 bucks. Skip a couple beers the next time you’re out to dinner and you’ll be money ahead.

Not everyone can 'just' go online and buy stuff; but thanks anyway.

Alrighty.
Have you explored this theory?:

Valve lapping compound is only $4, give or take. If the spring is indeed the issue, though, the only way to fix it will be to buy the replacement part. Not sure I see any way around that.
