It depends. On the gas port size, BCG mass, strength of the ammo you'll use, lots of things. Many people use the regular carbine weight buffer but an H usually works. I have an even heavier (+0.9 oz.) H2 in my ArmaLite middy since its BCG is the AR-15 style which is about 1/2-3/4 oz lighter) than M16 weight. I have the H in my Daniel Defense middy because it has the heavier DD BCG. The BCG + buffer weight is about the same in both rifles and low powered ammo cycles the action just fine. The H2 + DD BCG might not cycle but I've never bothered to try it.
You have to give it some thought then go with it. Too much weight then you might need a lighter buffer but they're not that expensive.
