Rather than retype it all...... copy and paste from my post in the last "what ak should I get" thread from last week
the Yugos will be built on a heavier duty reciever, heavy RPK type front trunion AND heres the best part the Yugoslavs changed the UF stock geometry so its in a straight line with the bore for a much more comfortable shooting Underfolder ALL others drop down about 15-20 degrees from straight when locked open thats why ya here folks complaining about cr@ppy cheek weld with underfolders etc... the stock falls away leaving your head sitting on thin air, this is not an issue with any of the Yugo based underfolders
I build all of mine primarily from virgin parts sets so can't say much about other builders products but for the price a Century built one is a good starting point.......
ya can also add a thread on grenade launcher to the yugo and really start havin some fun......
Specs for ANY Yugo UF;
Brand new hammer forged barrel (no they are not chrome lined they are hammer forged match grade barrels)
Built in tritium night sights
100% fully heat treated 1.6 mm reciever USA Made exact replica reciever by Nodak Spuds
Underfolding stock is in straight line with rifle bore as opposed to dropping away 15-20 degrees like all other UFs
Heavy duty RPK front trunion for much sturdier and solid front end as opposed to the flat trunions used on all other standard AKMs
Custom wood is now available as well as ULTIMAK front HG assembly if ya wanna go tacticool with it adding optics etc.. $104 for the Ultimak frontend
Original Yugo underfolder Side scope rails are available and very simple to install with either screws or rivets
Stainless bolt and carrier
Grenade sights built in and for $32 ya can get the removable USA made launcher for lots of dummy grenade fun (I add arial burst pyrotechnics to mine) ya CANNOT use the launcher on a standard AKM as they don't have the beefed up front trunion or a sturdy enough reciever etc..
Locking dustcover latch
MUCH more comfortable PG from the start
Well thats about it, as far as fit and finish that will depend on who built it, Century is a very good deal provided ya inspect for canted sights thats the only place they can really mess up
If I wanted the best AK I'd only consider either milled or a Yugo in fact the Yugos parts other than the reciever itself are all intended for a milled AK, add a $15 milled style recoil assembly and ya got ya all the benifits of a milled AK at half the cost plus the built in tritium night sights are something ya'll only find on a Yugo period
A WASR is deffinetly outa the running when ya compare what ya actually get for that extra $100
