Thanks for the info and mag offer Z. I will eventually have three mags on hand but one is on backorder and the AS shoot I am planning on attending is in June out a Lincoln Ike's. Its on the third weekend of the month. At least I hope to make it. I have found out that I will need some joint surgery on my right hand and that could change things but I think I will be able to schedule it so I get the shoot in first.
As for the bushing on the bolt carrier, so good so far but time will tell. At least if it does happen then a fix is at hand. I have a buddy who just picked one up a couple of weeks ago and has had no issues so far either. I had read before buying mine that some folks had a lot of break in issues like you, seems the Spikes uppers had the same problems overall too so I went with the somewhat cheaper TacSol. At any rate I have been pleased that up to now the units we have haven't shown us any problems. Its always possible that TS was listening to their customers and have made some changes by now. Like I said, time and shooting will tell. Got to say right now though the .22 AR upper has been one of the better buys I have made lately. At least I am getting in some range time that I just could not have afforded shooting .223.
