Found what I needed easily and got it quicl
The ring connects with a drift pin. After less than 100 rounds through my rifle, the drift pin worked itself out. Even after I reinstalled the pin, it just came out easier the next time. This should not have a drift pin. It should have a piece of hardware that will not come loose and cause the mount to fall apart. This is a design flaw. I'm not sure what else to recommend, but this is not a well thought out product.
Before I ordered this mount my factory sling mount in the front of the rifle was rubbing on the 3 point sling and the rifle just didnt sit right with tactical handguards. Now It sits perfectly after the mount is installed on the left side. Thanks again Bravo Company!
