Nope, you just got lucky. As much as it seems they never made a truly stellar product, most of their reputation was earned early on, and my own SGW stop sign AR always had the faint wiff of lemon, at least until I reworked it and replaced enough parts that it now runs "okay". They got away with a lot in the mid 80s when they were only non-Colt option on the market, but once Armalite and Bushmaster came online and showed the world that it shouldn't be necessary to hand-fit parts to make them work together the lustre came off Olympic Arms pretty fast, and it never came back.
