I only got to shoot mine two days on one weekend before they closed the range down. I liked it a lot, but I had to add a spring clip on the bolt in order to get reliable extraction. A spare spring clip from a MKII worked fine. Can't wait to try it with different type of amo. I only tried CCI Standard Velocity at 50 meter and it did not seem to like it as much as my MKII did. I will chip in again once I can go out and shoot.
