flush cups?

While I haven't ordered through them, in researching for a build I'm planning, it seems that Grovtec is a good company to use for flush cups.

I've came across them doing some research and I think it's what McMillan uses in theirs when you order a stock w/ flush cups, but they don't list prices on their website.
 
You should be able to order just the flush cups from McMillan. Just give them a call and have your credit card handy and they will fix you up. That is what I did.
 
FYI there are different cups available with full or limited rotation if that matters to you. If epoxy is used to set them permanently it would be better to get what you want. If they are the limited rotation be sure to click them correctly.

Grovtec are good quality cups at a reasonable price. I keep some on hand for guys. Magpul has some but unless you need them specifically are quite a bit more $ unnecessarily.
