I was one of the doubters on this thread. I ended up sending a lot of PMs and ultimately decided to buy one. Some of the abuse they’ve been put through by others is impressive. My long back ordered scope is finally at gun shop, so I’ll get to shoot it myself soon.For those of you who are worried that the R8 will fail to cycle when used in a dusty environment, it's quite simple. Pull the bolt from the receiver. Take your shirt tail and wipe out the recesses in the receiver that the bolt rails ride in. Then repeat the process on the bolt rails themselves. Replace bolt and voila! Problem solved.
