I like mine. To be honest, less than I thought I would. Once you've owned a Swiss Arms, this one is a lot more rudimentary. Still, it's a battle rifle and accuracy is what you'd expect.
Mine had a wonky mag that would always jam, but CSC replaced it no hassles. It's been 100% reliable since then with Norinco 7.62x51. Safety lever is small and stiff to operate. Trigger is good - about the same as a Swiss Arms. Charging handle on the SG542 is brutal compared to the Swiss line. Rear sights are much better on the Swiss. These irons are somewhat inelegant. Front sight on the Swiss is better by miles. You can really tell the Swiss Arms are a refinement of the SG540 series.
In all honesty - if I had to buy it again, I wouldn't. I like my guns a little more refined. But as long as you accept it for what it is (a very expensive M305

), it's a decent rifle.
Factory bipod is a joke - don't bother - and the folding stock looks as comfy as a chunk of re-bar. Mags are ridiculously priced, but no cheaper alternatives at this point. Perhaps when the TI shipment lands (???) and more people start shooting them, there would be a demand for aftermarket mags, but don't count on it.
