This really helps clear up the confusion, I appreciate the response.Buffers:
Under normal conditions just stick to standard weight (3 oz) carbine buffers with most builds. Short barrels under 13.7 likely will benefit from heavier buffers. Several manufacturers ship AR pistols with H2 or H3 buffers.
9mm is a totally different animal and needs special considerations to make sure it runs properly.
Rifle length and weight (5oz) buffer systems are normally seen on longer (18+) barrel configurations although they may also work on shorter systems. Because of their weight they may cause short stroking in cold weather with 18” rifle and 14.5” mid
Gas Systems:
-Rifle length gas 18-24 inch barrels. Carbine and Rifle buffers seen
-Mid length gas 14.5 - 18 inch barrels. Carbine buffer systems usually seen with these.
-Carbine gas 10.5 - 16 inch barrels. Carbine buffers here too. Sometimes these guys will benefit from an H1 buffers.
-Pistol gas anything under 10.5 with the exception of some 300 blk 16 inch barrels. Carbine buffers. Often times with heavier buffers as well.
Adjustable gas blocks usually just with suppressed use and/ or abnormally light BCGs I’ve never needed one personally.
Learning to read ejection patterns is going to help any issues. This might help as well

I believe the truth can only be found out once you sacrifice a rubber chicken while chanting "oh what a goose I am" while wearing one of the outfits from the village people!Buffers:
