The Olympia uppers are good, haven't had any problems other than the light primer strikes, which can be solved with the MGI bolt/firing pin per chad's advice.
The ER Shaw barrels have had mixed reviews on the interwebs, thus leaving me on the fence. Midwayusa.com has complete uppers with dealer pricing which comes pretty close.
