Over the years, ammo grew "hotter", as M855 has more "dwell time" in the barrel than M193, and functions at similar pressure, the effect is that more gas is used in the cycling with M855. Now we have Alpha 1, and so on...
Then take into account all the people wanting to run Tula, and the "We'll just hog out the gas port and it will run with anything!" that many civilian companies went with.
What is the problem with the CAR buffer, CAR spring, and CAR buffer tube? Does it actually HAVE an issue? My answer is: No.
The gas port has an issue. All in the world that the buffer is for, is to counter-act the rebound of the carrier, and a CAR buffer will do this, quite nicely. The gas port should be sized correctly so that only the excess gas required for adverse conditions is pushed into the system. Once this is done, you can run the weapon, reliably, with a CAR buffer, or if improperly done, poorly with an H3. The gas port is the devil in the details, here.
All my BCM's run fine with carbine buffers with everything from tula to expensive defense ammo. I constantly see on the internet that i "need" an H buffer "at least" but many thousands of rounds later the guns just keep chugging along with that wimpy carbine buffer. Guess me amd my guns are to stupid to know that they should be unreliable.
