The ASC 5 and 10 rounders work best in my RAP. The 5 rounders are the ones I prefer. 100% functionality. The 10 rounders will hiccup the last round occasionally. I shoot everything from 100's to 130's in factory and reloads. For the RAP, it's all about the mag spring tension. Hint..................it doesn't like a lot of it!
