This replacement part is an essential part of the cross bow. With out this arrow shaft guide the Ravin Crossbow, mine is an R20 Sniper model, will not function. That being said, I ordered this part as a spare just in case the original guide fails. I also ordered spare sets of strings and a bow press to replace the strings.
I should NOT have to replace this part..... I was "on stand" and noticed a roller was gone. Where's the quality RAVIN .....???????????
Disappointed !
You own a Ravin, you better have a spare in your pocket every hunt !
