I have a friend who's experience runs right along with that of Marco. He owns two of the rifles, one magazine fed and one barrel length tube fed, and he was exstatic when Centruian started making ammo for the rifle again. Until he shot some of the ammunition. It went bang every time but the bullets went numerous directions when they exited the barrel and it was very inaccurate in both of his rifles. He was so worried about it that he finally shot a few of his stash of old Remington ammo just to satisfy himself that the guns weren't at fault.
Now he has bought a CF conversion for one of the rifles which includes a new CF bolt head, dies, brass, etc. which he said were very "spendy" to acquire.
