Greetings,
I know ProMag used to make them, and they should again as there seems to be a keen market for a 5 round hunting clip for this rifle, and they can't be found for love or money anywhere. Where they appear, they are grossly overpriced or bid up to the stratosphere. I have no metal working abilities or I'd try to cut a 10 round magazine down and put a new bottom on it. I would pay someone skilled at this to do it for me with a 10 round clip if they can show me examples of their work and references.
The fact is, the rifle is technically illegal where I am located with a 10 round magazine, even if there are no rounds in it! [talk about gun law insanity]
I have searched all the usual places via Google etc. and come up empty handed.
Thanks.
