garu pretty much summed it up, but as for this line, to expand on it more.
each name (mold) has its own physical properties which govern the maximum legal weight (although there is no minimum). for a buzz, (~21.5cm diameter or so) will carry a maximum legal weight of 178g. also, discraft produces the buzz and very rarely produces discs lighter than 164g (and rarely below 167g in Z plastic). i have seen buzzes (in various plastics) ranging from 160 to 178g.
recently, more and more manufacturers are producing plastic in the 145-165g range, but these still aren't as common as discs in the 169-175+ range.
discraft elite x and pro d discs (as well as DGA discs which are also produced by them) will have a weight range printed on them that follows a 160-164, 164-166, 167-169, 170-172, 173-174, 175-176, and 177+ labelling system (although if you find old back stock they may be of the original 165-169 and 170-174 system from when they first started using stickers). in z plastic the individual weight should be handwritten on the rim.
most other companies will have it written on the bottom of the disc (or inner rim in some cases) and be in 1g increments. ching takes this to the extreme and has them weighed within 1/10th of a gram.
one thing that should be of note when talking about the written weights is that discs that are labelled at the maximum legal weight are often heavier than they are marked so it's often more accurate if you buy discs that are marked 1-2 grams below the legal max.
