Lefty here. Never had a left handed rifle in my life and have had plenty of semi autos. When I had my CZ scorpion evo I ran into the same problem occasionally. I put a brass catcher on the gun and the netting seemed to almost eliminate it. Bonus points is that because I was catching all my brass I didn’t have to spend time picking it up.
The program manger for the M16A2, a USMC Major was a lefty and hence the nub by the ejection port that helped lefties. Then no more hot brass in the elbow joint or down your shirt. They did make left hand firing adapters for the range in basic training but often unavailable but it just a plastic device that snapped on to the carry handle using the hole. There is YT video somewhere when he explains everything in the A2.
Stage Arms made the model 7 Hunter in a lefty version and 6.8 SPC and it works well for deer with Sierra Nevada 110 ProHunter pointed soft point bullets. I think Nosler bought them.
