| I need to purchase a buffer and spring for my Cav Aid lower. Is there an advantage to going with the heavy buffer over the standard? |

In my opinion, it would make no difference in a semi auto. The "H" carbine buffer(one tungsten with two steel) was developed because of a problem the carbines were having with "bolt bounce". A carbine runs faster in full auto than a full size rifle. The carrier would hit the barrel extension and bounce back a little. That would be the same time that the auto sear would release the hammer. The hammer would not only drive the firing pin forward, it would also push the carrier back into battery. The hammer spring is designed to push the firing pin forward, not the whole carrier. This would make for a light primer hit. If the round didn't go off, this would leave you with a live round in the chamber and the hammer forward. The tungsten weight added two the two steel weights in the buffer hit a fraction of a second after the carrier and buffer hit the barrel extension. This second hit holds the carrier in place. Unless you are looking to get into "bump firing" or buying a registered sear, the "H" buffer won't have any effect over a standard carbine buffer. Scott |
