THE IMAGE ABOVE IS A PAID ADVERTISEMENT I'm thinking it's wise to have a few spares, looked in Brownelles and found several brands, Which one to stock up on? Also have some M 4 types, same question. Thanks |

Thanks Usually reduced power, standard, heavy. Sprinco, Wolf or Tubbs. In carbine it's useful to have an assortment of buffers. |

Maybe I should have asked which to eliminate the double feed and failure to hold bolt back after last round? ( Have tried new mags) thanks

That is if the gas port is aligned correct and the gun is well oiled. Sounds like you may be under gassed, what buffer is in the gun now? I use a GI spring and change buffer weights as needed. I did use a springco blue spring in a pistol build. Having different spring rates to work with is a good tuning aid IMHO. |

The H buffer 3.8oz, H2 buffer 4.6oz and the H3 buffer 5.6oz. Normally you would use the heavier buffers for a over gas condition. Having a unmarked, H and H2 should cover about all over gas problems you well see. Short stroking with a carbine buffer I would inspect the gas system from end to end. There are several places that can develop a leak. You can open the buffer and play around with different combinations of the weights. Rifle 5.2 oz Carbine 3.0 oz -> 3 steel weights H buffer 3.8 oz -> 1 tungsten weight H2 buffer 4.6 oz -> 2 tungsten weights H3 buffer 5.6 oz -> 3 tungsten weights ST-T2= 4.3oz. ST-T3= 5.4oz |

I really dig research, where did you get this info?
