Steyr Pro Hunter / Safe Bolt System Hi-Capacity Magazine Extension and Mags

[JohnnyVolume]

I'm looking to upgrade my Steyr Pro Hunter/SBS and I am looking for a Hi Cap Mag extension and Mags in .300 Winchester Magnum.

Any idea where I might be able to find these parts?

Thanks,

Johnny Volume

Check the Steyr website. I have not seen an extended mag for any of the short mags, let alone the standard mags. Let us know how you make out.
