So i put a new AI prime on the bc14 and due to all the negative reviews about the rail arm that people posted i decided to go with the new flex arm. Its very easy to install however the set screw for the post was to short so i will need to replace. 12inch arm should have been ordered over the 18" but again it is adjustable so you can put it where you like. I know there are very few reviews on this so thats why i thought i would share.
