I've got a 527 in .223 Rem., but not the carbine, the longer version (Lux). I love that rifle. IMHO the price is OK with the Leupold scope mounted.
But here comes a word of warning: if you plan to use a cheap surplus ammo with steel (magnetic) jacket - not case, the bullet jacket which is in contact with bore - you will hurt the gun. Typical AK ammo like that is expected to be used in AK which has a hardchromed barrel, and kills any normal bore even if it uses non-corrosive primes.
I hear that the new Wolf (Barnaul) ammo is better than before and that they are using some very soft steel for the jackets, but I personaly do not dare to use the cheapest stuff in my gun anyway.
So, the rifle is a great handy gun and sweet to shoot, but if you want it solely because you can buy the cheap ammo, it's not the best idea.
