[QUOTE="cdragen, post: 3645505, member: 48392"] Well, I have a small update from today's visit to the range. Still having issues cycling, even though it seemed to be fine at the end of the previous trip, so in between shots re-zeroing the scope (which mounted fine and seems to be holding zero fine in spite of the fall--more on that in a minute), I attempted to adjust the gas on the Odin Works adjustable gas block I was smart enough to install (*patting self on back continues*...). I wasn't seeing any progress in fixing the cycling issue and decided to open it all the way up and then take it down a notch every shot until it wouldn't cycle again (following the instructions!). Well, I might have gone a little further than was strictly necessary when opening up that gas block, because the next shot felt markedly different and the bolt had hardly moved (when it should have been the opposite). When I went to make another adjustment I realized the gas adjustment screw was conspicuously absent. Whoops! I then wasted about a minute walking forward and looking down at the grass until I realized that I was being stupid and I was never going to find what had essentially become a second bullet with all that gas launching the adjustment screw downrange. So I ended my range day early--again. I feel a little embarrassed at striking out twice, but then when I started this build I somewhat expected issues, just not like this lol. I also feel like the cycling issue may not be entirely due to gas or lack thereof--pulling the charging handle to cycle the bolt seems much more difficult than it should, and I think I may have dismissed it the first time around since I hadn't handled an AR 308 before, but now I'm almost sure that the buffer spring I have installed is too tight. It was a no-name brand since I figured I would be tuning everything at the gas block so a tightly spec'd buffer spring wasn't really necessary, but now I'm thinking I might need to trim a coil or two (maybe by halves) and ease up the tension in the buffer to something more reasonable (and if that fixes it probably purchase a different spring).
