I just got my Maple Leaf receiver in the mail, and immediately noticed how much better its internal centering ring is- just so much smoother than the stock one. However, it doesn't come with a front ring.
The bolt slide has already improved greatly, but it got me wondering about that other ring.

Has anyone purchased either of the following rings?
VSR/Bar-10 Cylinder Centering Ring (CVVZ5PDNB) by Fsousa
VSR nylon cylinder Receiver Rings | PDI Parts Installation | Socom tactical

Have you purchased some other rings?

How were they?

Thanks in advance for any input!

These work better than the stock rings

And they have two sizes depending cylinder type
