I'm toying with some different buttstock ideas, and was wondering if somebody could grab a ruler and tell me how long the rifle & carbine buffer tubes are? I guess the critical dimension is from the front face of the flange to the back end of the tube, just to be consistent. Also, are those the only two common variations? I looked on-line, and couldn't find anything. Thanks! |

There are shorter "entry" stocks as well as the A1/A2 rifle and 2,3,4-position CAR stocks and the 5,6-position "M4" stocks. I have a 4-position CAR, a 6-position M4, and an A2 fixed stock I'll measure for you in a minute. BRB... ETA: Didn't want to remove the stocks, so I measured from the very back of the receiver to the end of the extensions. That way, I only had to slip the stock bodies off. 6-pos M4: 7.25" (it's sloped on the end, so I measured to the middle) 4-pos CAR: 6.75" A2: 9.625" Here's a "stubby" stock too, but I don't have one to measure: www.bushmaster.com/shopping/buttstocks/9349119-s-kit.asp |

Thanks for the measurements! Unless the two short buffer tubes are bored out to the same depth, the three lengths implies there must also be three different sizes of buffers out there. Otherwise one of them is going to bottom out too soon or too late. I've only seen two styles of buffers, although the carbine ones come in various weights. I'll have to dig around some more. Do you recall if there is any difference in the length of the internal buffers for the two short ones? |
Actually, it makes no difference because the tubes are bored out to the same length. There is a solid portion at the end of the longer tube. |
