Welcome from Iowa!
You can bandaide that system up with an adjustable gas block and maybe changing port size, hard to know for sure without more info. There is also more of a break-in with these large frames, more surface area to mate, small gas leaks that will seal up with rounds, BUT it will be a much more reliable rifle with the proper spring and buffer weight, years here reading along as people throw money at this issue, myself included, shows me just starting out with the correct stuff is simplest and least expensive. Now I promise the CS at Aero will argue all day long on that...... or just tell you to get a rifle buffer system....which coincidently has the correct weight buffer.
