My vote would be Carbine.

H2 is okay to use but I run the standard $25 RRA 9mm buffer in all my M4s.

How much do they weigh? Same as an H3 (5.4oz)?

Why? (Not being a jerk, I'm genuinely curious)

Colt 9mm bufffer is 5.2oz

Strat: my understanding is that the heavier buffer will reduce the cycle rate of the weapon which will also reduce wear on components, but more importantly should also reduce the felt recoil.

Years back the topic came up with regard to utilizing the heavier 9mm buffer in not only the 9mm pistol caliber ARs but running them in a standard carbine or M4 set-up.

As RRA sold them for the paltry sum of $25; I purchased one and placed it into one of my M4s in place of the H2 standard M4 buffer.

I LIKED the way it altered the recoil impulse and slowed slighly the cycling of the BCG to the point wher I bought another, and then another and then another ad-infinitum until one day it turned out that all my carbines and M4s had them.

Many folks think it's cool to utilize the M16 carrier for the same reason, in that the added weight tends to slow the BCG cycling speed improving reliability and IMO using the 9mm buffers accomplishing the same thing for little cost - and I'll never have to explain to any BATF agent why I'm running M16 parts in my M4s or carbines.

I have never had any stoppages or malfuntions in any way related to the use of the 9mm buffer in any of my AR15 rifles and prefer the lessened felt-recoil impulse which allows faster follow-up shots due to the less muzzle rise.

That's why I run them.


ps - sometimes it pays to check out different products - this is one time I was glad I did

fwiw, I'm even running an Endine buffer in my 6.8mm SPC carbine bought initially so I could compare the Endine with the 9mm RRA buffer as there's a significant difference in the cost and while the Endine is slightly better IMO than the cheaper 9mm option I chose to utilize it where it would gain me the most benefit - in the larger caliber....

Excellent answers gents, I'll have to try one out. Thanks.
