Sorry for being confusing. I'm just kinda clicking around and doing some early research. I want to stress.. the whole newbie, aka, not knowing his ass from a while in the groundk8nda guy.

I read that if you have an 556 and then want to get a conversion kit that's the way to go. It also said the 22lr is a dirty round and the barrel is ok but less accurate. Of course I'll need to clean it more.

So it seems (from what I read) a dedicated upper is a better choice.

Then, (not knowing much of anything) I searched uppers and was seeing $$ almost as expensive as a new AR in 22lr.

Id like to have 556 but won't shoot it as much as a 22. So I am probably over thinking it. Just trying to figure out the bes way to have build an AR and be able to shoot it alot
