I tend to agree. A lot of folks live some distance from where they shoot, and many have to pay range fees, that plus the gas money kind of leans me toward making sure I solve the problem versus multiple range trips or rebuilding a part at the range.
Especially since, based on the OP's description, it is an issue confined to one BCG.
Check the key for leakage, make sure there is nothing obstructing the gas passage, use the gravity method to check the gas rings. Someplace during this process you should have looked at the extractor, if not, do so now, make sure it isn't chipped and is clean.
Then, here is my hillbilly way of checking ejectors: BCG placed horizontal in the padded vise, carrier key up, bolt extended. Take an empty case snap the rim under the extractor and press it firmly against the ejector - I use my thumbnail to hol it in place. Then I stand to the side,slide my thumb nail off the case and let it fling. With the bolt fully extended I find the cases generally hit the shop floor about five feet away. I 'developed' this method after reading an article on ejector tuning for service-rifle shooters and decided to try it out.
I think that mostly you'll find that if anything the ejector is slowed by being cruddy, not the spring sacking out. Generally a disassembly and cleaning will put you back in action. The OEM spring is pretty stout for the job - I've cut up to four coils off an ejector spring and had it still function - don't do this on anything but a rifle shot strictly for fun or competition.
All that being said, unless you want to get something that has been fondled by a Volcano Virgin, you can buy a bolt rebuild kit for under $20.00.
