Yeah...if you watch the Bore Buddy video on the buffer weight page, there is quite a bit of bolt bounce with the plastic buffer.

Although I also run the Taccom buffer spring. It ran fine with the original, but I just wanted to get everything fresh. I plan to change to the Taccom stainless extractor as the only malf that I had during one stage was an FTE. It took me two tries to get it extracted. The hammer hits so hard that if it FTE's and gets hit a second and then a third time, that brass has some deformity.

This is an old Super X brass hit 4 times. (I used it to dry fire test the trigger). You can see how hard it hits...and it isn't even the green heavy springs -using the medium because due to tolerances, the green ones slightly rub the lower and won't work reliably unless I polish out the lower where it rubs. This also will bring the trigger weight down too. It is light enough as it is though.
