| hi guys, got to looking at a buffer last night. it rattles, it makes me think that the plastic piece can be removed and lead shot can be installed? anyone tried this? i know it would have to be weighed before and after and go from there. but if its possible to do this then, i am going to do it. |

Many of the cheaper buffers use steel sections seperated by rubber wafers. They are held in by the bottom plastic/rubber piece, which is in turn held in with a roll pin. You can tap out the roll pin and play with it if you like. I"m at work right now, but I don't know how much weight you're going to gain simply by putting lead shot in the cavity. Might not be worth the effort. I would recommend that you simply purchase the correct buffer if you want a heavier one. Can't argue with the reliability and peace of mind of having the right part. I got creative one day and put some bar stock in my lathe and made a steel 5 oz buffer. Worked so well in my adjustable stock lowers that I made a few of them.

I took a 2.9oz CAR buffer, filled it with #8, and it weighed the same. I have a std rifle buffer, weighs 5.1oz, machined a solid dowel from brass, and now buffwr weigh 7.0oz. We tested it with a M16 w/rifle stock, and 11.5" pipe, fella thought it felt slight smoother and slight slower. This buffer is going on a MAC 11/9 slowfire. |

The Rifle buffer contains 5 weights with separators. They do slide around, by design. The CAR buffer has only three weights due to the shorter lenght. The purpose of the sliding weights inside is to act as a deadfall hammer, to help prevent the carrier from bouncing. There are some cheap black plastic CAR buffers filled with BB's. I have seen at least one rifle that had doubling problems that were cured by replacing the cheap BB filled buffer with a good quality normal CAR buffer. I have no idea why this worked, but it did. |

Interesting thread on using tungsten to increase buffer weight... www.ar15.com/forums/topic.html?b=3&f=12&t=200691 |
| I would recommend against using lead shot in a buffer. After some time, the shot will work against each other and turn into lead powder. Rather, I would suggest filling it with molten lead. You can calculate the displacement of the buffer and melt the appropriate amount. Lead weighs 6.55 oz per cubic inch. The steel that you would be replacing would weigh 4.5 oz per cubic inch. Calculate your desired weight from there. |
Herzo, Carriers need anti rebound ability, this was learned waaaaaaaay back in the day, one reason for the demise of the Edgewater buffer system. |
| leave it up to me to think too quick. lead on lead not so good for a fella but the turning one out of brass idea sounds good. bismuth weights? man i knew i should have gotten that lathe awhile back. but nooooo. i can see its going to be a slight problem converting the buffer. hell if it werent so dangerous, mercury would be the ticket. |
