This is probably very simple but I am drawing a blank. What does "OPTIONAL MK-319-BS ON BOTTOM SIDE" mean. I cant find a reference in the manual and I searched for it here.
It is for an RV-8 but I posted in general hoping it is a universal instruction. Thanks in advance for your help.

The MK-319-BS is a blind rivet (or pop-rivet). It basically means if you aren't able to buck the AN426AD3-3.5's as called out, you can use the specified blind rivet. It also says you should only use it on the bottom so people don't see it on the top side of the finished stab.

Thanks guys, you are THE best! Now I have the two follow up questions.
1. Anyone try to buck these...or is it best to just pull them and don't even try to be the guy hoping to prove something?
Second question...probably for Spike...how do you remove the stupid questions you post so you don't broadcast your ignorance to the world!
Thanks to all. As you can see, the dinner at the Otter got the blood flowing again. Special encouragement came from Painless and Brad Oliver. Those steaks must be fortefied with high levels of "get her done!"

You get to leave the postings so that other people with the same questions who are too timid to ask can see the answer!
As for bucking versus blind riveting, do what is best for you in these situations. Lots of people get hung up on never using blind rivets. I personally say "bah!". Just build it

I guess I fall under Spike's category of being one of those people that "get hung up on never using blind rivets". I have gone to great lengths and hassle to not use blind rivets unless absolutely necessary. For me its about pride in my workmanship and not getting the thing in the air ASAP.
Either technique are acceptable methods for building. The issue with using solid rivets in tight spots is it can be a real pain if you mess up bucking it and you drill it out incorrectly. If that happens, you may not be able to put a blind rivet in, and use an OOPS rivet. On the flipside, if you do tackle these more difficult rivets, it will make you a better builder. Eventually in the build there will be spots where you are going to have to tough it out and install a pain-in-the-ass rivet.

I also fall into the category of using solid rivets if at all possible. I did the ones you point out even before I had my tungsten bucking bar, which by the way makes doing some tight spot jobs way easier.
If the plans say it is acceptable to use a pulled rivet, it is from a technical point of view, an individual builder may decide if he/she wants to exercise that option. I can say that sometimes it is just a matter of doing things in the right order to make it easy, while others can be a lot of work to use a solid rivet because a special setup or tool is required.
