I have the volquartsen DLC Competition bolt in my Mark IV Competition, and I LIKE IT !
Thats what I was thinking considering what all you get with it. I am very happy with the DLC finish on my 10/22 bolt.I just ordered one and it'll be here next week. It's worth $99 to try.
Wait! You’re supposed to clean these things?The reason to get this coated bolt is not primarily for the performance or reliability, it's for the ease of cleaning.
