I have the .223 version and it has had numerous extraction problems, I've not had a chance to troubleshoot it however. On 5 occasions out of 40 rounds it has failed to extract the fired casing, so the bolt strips the next round from the magazine and smashes it into the fired casing, resulting in the bullet being pushed in and powder everywhere which is fairly annoying. I did a detail strip and clean/de-grease and double and triple checked the extractor function so I'm hoping for more trigger time in the spring with positive results. Very little recoil and I've been minute-of-playing-card at 50 yards with it so it's fun noisemaker.
