We have had so many calls and email about H2 & H3 AR-15 buffers that we have decided to sell the individual tungsten weights. Simply drive the roll pin from your existing buffer and replace the copper or steel plugs with these high density tungsten. The plug dimensions are :  0.555 diameter x 0.600″ tall. Sold individually or as a 2-pack.

This is the breakdown for how buffers are rated :

1 Tungsten & 2 Steel (or copper) = H Buffer

2 Tungsten & 1 Steel (or copper) = H2 Buffer

3 Tungsten = H3 Buffer
