Another thing to consider is bolt bounce which can aggravate any of the issues already mentioned, especially the running dirty part. In my non-expert opinion that could be a problem without proper lubrication. I keep mine wet. Get some high speed footage of your bolt cycling with your low mass components and see what happens.
Also consider that you're making your AR more sensitive to magazines by marginally increasing the cyclic rate. Think of the all too common bolt-over-base malfunction with overgassed and/or suppressed weapons. All this probably means - at least all it means for me - is that you want to keep some new-ish mags around for any "serious" purposes, and not rely on those beat up GI mags you've been taking to practice sessions for years now. Just by purely subjective measurements I get the feeling Lancers have the strongest springs on the market.
For myself, I'm running a rifle length 18" with a Syrac gas block, A5H0 buffer (3.9oz) and a Young NM Lite carrier, neither of which are quite as light as the corresponding JP LMOS components. I dig it. In the future I might feel the need to push harder for more weight savings, in which case I might empty out the buffer, but that day hasn't come.
My other rifle though is a 16" middy with the same Syrac, but a full-weight A5 buffer and a BCM BCG. So maybe that makes me a hypocrite. Haven't shot it yet though, and I don't think I'll have much of an objection to tweaking the buffer weight a bit - maybe down to the A5H1 range.
I don't see any reason why I wouldn't keep either rifle loaded at my bedside or something, as my standards for reliability are the same for all of my guns no matter their purpose.
Oh, and TBK, you suck. <3
No issues with premature unlocking but of course you should run one with adjustable gas. They are common in three gun among the top shooters. The only issue I have had is chambering the first round when the gun has been fired more than 200 rounds or so. Usually hand cycling it will not work. I have to drop the bolt from the locked back position. I just started cleaning the chamber before every match. No more issues.

Does high-reliability for you mean lock back on empty when shooting weak .223 (i.e. Tula)? Are reliable feeding and extraction as important to you? Honest questions here, no sarcasm.
I think low-mass components make your AR more sensitive to variations in magazines, ammo, being dirty, amount of lube, environment, etc. In other words, the window of reliability shrinks. You can tune it to run fine under a certain set of conditions, but step outside of that and the gun is not as forgiving as a stock rifle from a reputable brand.
Just for fun, my dream soft-shooting duty/defense build would have:
17" midlength barrel
Syrac GB
LMT Enhanced BCG, carrier NiB coated
Vltor A5 with A5H4 buffer
Sprinco Green action spring
GA Flash Comp or Proto Z-Comp
I have no idea if it'll work... maybe I should build it and find out.
Then you are going in the wrong direction. By "fine tuning" a low mass rig, you are by design, "de-tuning" the reliability to make the rifle function within a much narrower margin, but to perform BETTER in that narrow margin than a more reliable rifle would function in a larger margin...
Confused or enlightened?
what is the narrower margin?
Seems seems like people generally "tune" their rifle by changing out Buffers or BCGs, because they cant change the size of the gas port. If the gun is under gassed they make it more reliable by going with a lighter buffer. If its over gassed, they increase the buffer weight. seems like if you have a set weight for the buffer, BCG and tune the gas port, it should be reliable. Although people have said the lighter BCG makes it have less force to seat a round, but others say they run it in carbine classes and shoot the piss out of it and it works great.
So far both my tuned rifles (11.5/16) have been 100% after a lot of shooting and no cleaning. If i used a lighter bcg, will that jack everything up?
