It really depends on the particular weapon. All WASR-10s are not made equal. The postbans are a little tricky, Century was in no way surgical about the conversions.... the magazine may have a wobble to it, and the front sight may have a slight cant. Otherwise the /63 is a hit or miss and some may be better, some may be worse... The difference is that the old ones were made with rejected parts (safe for semi only) .. the new ones have demilled parts... like yours with the triangle/arrow (better overall). Check for matching numbers. Decent furniture, matching numbers, and the triangle on the trunion will usually put the value in the $500+ range, where the older WASRs will be -$400.
Many people have no idea what they're actually buying anyways, so someone could very well get a POS for $600.
I have a /63, traded it for some Johnnie Walker Blue Label... sanded/refurbished/stained the wood, fixed the sheppard's hook, tightened the mag well, fixed the trigger slap... it is suprisingly accurate and an overall fun weapon to shoot.
