About a year ago I bought my first AR, an simple but new PCR 99 by Olyarms, 16" standard barrel, beautyfully crisp factory trigger, Tweakers 3-9x28 ar15 scope. Is is a pleasure to shoot, often outperforming rifles like the SIG, with <1" groups of 10 at 50 metres as well as performing very nice in Dynamic Service Rifle matches(with Beamshot 1001 lasersight), and my 30-rnd Thermold magazines drop free at the push of the button.
I feed it PMP surplus ('85-'89) SA army rounds, not one misfire, no stuck cases, etc. It cost me the equivalent of $720, which for Dutch pricing is relatively cheap, and I'v enjoyed every shot I, and a lot of friends, fired with it through its non-chromelined barrel, maintaining it once per month.
The money it cost less than Bushmaster etc. I spend/t on accessories like sling, Harris bipod, etc.
In your place I wouldn't hesitate to buy the rifle, but my Dutch merchants mind I'd try to lower the price a bit [:D]
