I'm a little confused here and could use some help.
I recently bent the spear for my riffe euro 130, and am looking to replace it. I may be wrong here, but based on all the searches i've done here, everyone's riffe comes standard with a square shaft, yet mine which i got from the local dealer came with a round notch..

It's an issue because the only spare shafts i may have access too may be square notched (not sure haven't quite made it to the store yet)...
Everything on the forum i find raises the opposite issue, i.e. people with riffes wanting to use a round notched shaft
