I will say that I'm not an expert of flow dynamics, by any means, and have only owned suppressors for less than a year, but I have been doing quite a bit of reading and have been shooting for 40 years. That said, I don't think that all the effects of a high back pressure suppressor can be mitigated with a smaller gas port and/or heavier buffers in an AR. My understanding is that while a smaller gas port will help mitigate the gas pressure used to cycle the action and both reduce action speed/violence and prevent too early unlocking, it does little to mitigate the increased gas and carbon coming down the barrel from a non-flowthrough suppressor. IMO, a flowthrough/forward venting suppressor is the only way to mitigate this.
However, if a flowthrough can isn't available to you, you should definitely go with an adjustable gas block, or preferably a restricted gas tube from Black River Tactical. Available here: https://blackrivertactical.com/WP/Ad...Drive-c6464009 They really work, and don't have the issues that an adjustable gas block has. And as Wake27 wrote, a heavier buffer will also help, but I would get the adjustable gas block or restricted gas tube first before messing with the buffer.
Tell us a little more about your rifle, if you don't mind. Barrel length, gas system length, buffer weight, manufacturer, etc. It will help people give you more accurate advice.
