Have you done any recent amount of business with SurplusAmmo? Used any of their name branded products?

I have not.

But when I've checked up on them in the past, the info that I got led me to believe that I can do w/o dealing with them.

On the other hand, AR parts are becoming more available, with maybe the exception of barrels, & prices seem to be stabilized or coming down to pre-panic levels.
