I developed this quiver holder a couple of years ago and it has risen in popularity ever since.  It is offered in both a Right side and Left side version and once again, offers some advantages over the standard Ravin design,
 
In many cases, you can put your R10 in the Ravin soft case without removing the quiver.  However, if you have both the stirrup and a thick stock spacer on your R10, the added length can be an issue that might prevent this.  
You also don’t necessarily need to remove the quiver when hunting from a ladder stand with a shooting rail.
The custom design of the 3 piece assembly that actually grips the quiver allows for 1 hand removal.
It’s simple to install and locks into place on the Ravin riser on all Ravins but the R18 and R500.
