Have you had your conversion kit malfunction whereby a live round jams itself up into the TOP of the unit? It’s very irritating. That Remington ammo does this a LOT. The resolution is to just remove the bolt, or reach in with a Leatherman tool and PULL the stuck round out. :-)
Yes - happens a lot. If i clean the unit frequently it does not happen. Also - important to pull trigger and let go!
It overfeeds if you dont let the trigger up.
