I bought it last summer NIB for $390. Currently I have ran around 300-350 rounds through it. At first I had a lot feeding problems. I tried three different makes of CCI's. So the next time out, I tried some Remington bulk. It did cycle a heck of a lot better. The one thing that did eritate me, is the fact that you had to force the magazine to get it to lock. I also took the mag apart, and cleaned it because there was a lot of wax buildup from the CCI's. Well a couple of weeks ago, I took her to the range for the first time this year. Wow can you say FTF's constantly. It was like every 5-6th round. Exact same ammo, out of the same bulk pack that ran great last year. Towards the end, I would just load three rounds. The first would feed just fine. The second round would not feed. When I pulled the bolt back, the new round would be sitting verticaly. Every time the same thing happend. I did notice a crack in the back right corner of the mag. Do not know if that is causing the problem or not. I'm pretty disapoined considering what I payed for it. When I have a $130 597 sitting in my safe, that has had 0 problems. So I have two choices. Sell it, or pay $25 for a new mag and try polishing the feed ramp.
