Try this, with the magazine in the gun and the gun field stripped. Push the shell down with your finger as close to the rim as possible and applying a slight rearward force, you want to push it until it is below the bottom tip of the last round bolt hold lever.. Now let it rise slowly and see if it snags the last round bolt hold.
You need to check a couple types of shells and at full and nearly empty capacity.
Once you have an idea of if it is catching at how much, a couple light taps to the tip of the lrbho lever will often correct it.. Be aware that there are NO replacement levers so proceed with caution. It does appear that the tip of the LRBHO is not bent to 90 degrees and is slightly open causing it to go further into the magazine.
