problems with new .308 build

[shesky]

First of all, thank you guys for your help. I have built many ar-15's without issue and did not research the build problems that could be associated with an ar-10. I did eventually get some snap caps to run and the action seem a bit smoother but when I exchanged the bcm charging handle with a generic ebay version, it was like night and day. No issues(at least with snap caps). Unfortunately(and for most of the country) taking it out to the range is out of the question with the weather we are having. Hopefully it will clear up one more time before winter sets in but I'm not counting on it.

thanks!!!

While you're at it, I'd also triple check that the gas key isn't slightly loose - it might be tacked down vertically, but if it has some yaw play in it, those can bind on stuff (and have the severity affected by what CH is in use). May not be the exact issue in question, but an odd one I've experienced that manifested similarly (but not in the same way).
