Well I finally found a Mag A riser now I would like to know if the Bear 4 arrow quivers that attached with 2 screws in the riser are the brackets reversible to fit a left handed bow seems to me I remember them being that way.
Thanks
Dave
PS I will post some pics of the riser when it gets here.

The Mag "A" (metal) riser didn't have a top and bottom quiver mount holes. Perhaps  a hole was drilled later, or sometimes the medallion was removed and that hole was used for the quiver. There is also a small hole just above the grip for access to the side plate adjustment screw.

A picture of the riser will be a big help.

The Kodiak bow quivers( long with two bolt brackets) are reversable. I have one-new in the box.

I will be away from the computer until Monday.
