Thanks for all the replies, Fellas.
Well, there goes 820 rds of Malaysian M193 '81 lot 37.
All were clean and bright, with a few having very slight tarnish(nothing like Guatamalen), and
a smell not unlike that of an Oriental grocery store.
On 2 different occasions:
Weapons-BFI M4gery 14.5" 1/9 twist bbl/Aimpoint ML2, RRA M4gery 16" 1/9 twist heavy bbl./Eotech 552, RRA M4gery 16" lightweight profile 1/9 twist bbl./Aimpoint M68 CCO.
I experienced NO functional failures what so ever.
I don't have a chrono, but the ammo was nice and hot as when shot side to side with XM193.
Accuracy was OK. Not nearly as good as XM193 or The excellent Winny .223 Israeli Value pack. From a bench rest groups were around .5"-3"s in 5 round groups @ 50 yards. Under the same conditions @ 100 I was landing 3"-7" 5 round groups. Groups opened up towards the latter a bit during the second day with 6-8 MPH winds.
The stench was slightly sharper than that of comparable M193 rounds, however I was pleasently surprised it left less carbon residue and gunk than XM193 or WWB. Clean up was pretty easy.
I would definetly buy more if it ever became available and the price was right. Being true M193 albiet a bit old, with slightly less accuracy then domestic XM193, I also wouldn't hesitate to use it for whatever SHTF reasons.
