Yeah tell me about it. I looked for half a day until I ran into those on Wing Tactical. Like I said I have a 3.8 oz. ( I called PSA to get the weight ) short buffer with the extra power spring which which will probably yield the same results. If you want it, it's your. 25 shipped. It will cost probably close to 10 bucks to ship so I am not looking to make a load off of it. If it will help you out I will send them. The heavy buffer cost 45 bucks so you will probably save money. The whole idea is to slow the cyclic rate down and absorb rearward force so the spring should do the same thing.Found a BCG at PSA but not a single 308 buffer of any kind.
