I had a partial case head separation using a 1.8oz buffer

Actually - it's a full Odin BCG and bolt - here's the exact item I purchased:

One other interesting bit about the pistol is I put a Strike Industries short pistol buffer tube with a 1.8oz buffer on it:

Would a light buffer potentially put extra strain on the case a bit early? It's a carbine gas system.
