G&P Aluminum Buffer for TM M4 MWS Gas Blowback Rifles (Type: Short Buffer)

"Very nice buffer. Looks more realistic than the original buffer but maintains the front bumper to lock into the MWS bolt carrier.

Because the original MWS buffer has a spring loaded rear, that causes the bolt to cycle forward very fast and the MWS can cycle so fast it causes jamming issues. With a buffer that uses a solid rubber buffer, the bolt cycles just slower enough to aid in reliability.

The buffer empty is 25grams and each of the three weights are 14g. I recommend picking up 0L rubber washers and set the buffer up as rubber, weight, rubber weight, rubber, weight, so the shifting weights stop bolt bounce like real buffers work. I added a real tungsten weight (40g) and use two of the G&P weight to have a weight of 94 grams for my buffer. Heavy enough to give stronger recoil but still gas efficient.

I heavily recommend picking up this buffer to test around with your own gun. Either to add more tunability, have another key of realism, or improve reliability
