I'm not sure. Kartek lists that FK and Aurora bearings fit in their cups. I would assume QA1 are the same size, but I'm not entirely sure. The cups from Kartek are not much more, I think $20 or so versus what $12? It doesn't add much to the cost. The FK bearings are more expensive, and the Kartek misalignment spacers are more. But the machining quality on the spacers is far superior. I feel like Ballistics machining quality has dropped off a little bit from when I first started ordering from them. I have had to de bur, file, and even cut down several spacers I got from them within the last 6-8 months. I was pretty turned off by the fact that I had to modify them. Once I got a hold of some Kartek ones though, I will never go back. I like the look of the Karteks better too. Some of their spacers are more, like the 1" to 9/16" that does 40 degrees each way that I got, they are like $14-15 at wholesale (not sure on the percentage I get), so I would imagine that they are around $20 retail. That adds up quick, but their smaller spacers are very competitive in price.
